Kamailio out-of-mem

06 Jul '16

I'm running burning tests against kamailio and after some time ~ 2 days I see kamailio out of mem: ERROR: tm [t_lookup.c:1271]: new_t(): ERROR: new_t: out of mem: ERROR: tm [t_lookup.c:1411]: t_newtran(): ERROR: t_newtran: new_t failed The result of command kamcmd mod.stats all is: Module: core { sip_msg_shm_clone(494): 10653392 build_req_buf_from_sip_req(2149): 2565480 msg_lump_cloner(978): 2943584 create_avp(175): 969736 xavp_new_value(94): 858469320 counters_prefork_init(207): 16896 cfg_clone_str(130): 88 cfg_shmize(217): 744 init_pt(110): 8 init_pt(105): 8 init_pt(104): 3080 dtrie_insert(157): 240 dtrie_insert(148): 48 dtrie_init(60): 160 dtrie_init(51): 32 register_timer(1011): 360 cfg_register_ctx(47): 32 init_tcp(4635): 8192 init_tcp(4629): 32768 init_tcp(4621): 8 init_tcp(4614): 8 init_tcp(4607): 8 init_tcp(4601): 8 init_tcp(4589): 8 init_avps(90): 8 init_avps(89): 8 init_dst_blacklist(437): 16384 init_dst_blacklist(430): 8 timer_alloc(514): 96 init_dns_cache(366): 8 init_dns_cache(358): 16384 init_dns_cache(351): 16 init_dns_cache(345): 8 init_timer(283): 8 init_timer(282): 16384 init_timer(281): 8 init_timer(280): 8 init_timer(269): 8 init_timer(237): 8 init_timer(220): 278544 init_timer(219): 8 init_timer(206): 8 cfg_child_cb_new(830): 64 sr_cfg_init(361): 8 sr_cfg_init(354): 8 sr_cfg_init(347): 8 sr_cfg_init(335): 8 sr_cfg_init(323): 8 shm_core_lock_init(153): 8 Total: 875992224 } Module: dmq { alloc_job_queue(229): 128 shm_str_dup(723): 24 build_dmq_node(156): 448 add_peer(67): 168 mod_init(243): 8 mod_init(237): 96 init_dmq_node_list(66): 24 init_peer_list(33): 24 Total: 920 } Module: auth_db { Total: 0 } Module: dialog { init_dlg_table(284): 131088 init_dlg_table(276): 8 init_dlg_table(269): 8 init_dlg_table(264): 8 init_dlg_timer(57): 8 init_dlg_timer(48): 32 new_dlg_profile(187): 624 Total: 131776 } Module: rr { Total: 0 } Module: xlog { Total: 0 } Module: kex { pkg_proc_stats_init(79): 1056 Total: 1056 } Module: db_postgres { lock_set_alloc(70): 80 Total: 80 } Module: pv { Total: 0 } Module: textops { Total: 0 } Module: htable { ht_cell_new(183): 1104 ht_init_tables(381): 8388608 ht_add_table(278): 928 Total: 8390640 } Module: sqlops { Total: 0 } Module: tm { build_uac_req(1543): 848 prepare_new_uac(479): 28880 _reply_light(542): 751504 build_local_reparse(341): 1168568 relay_reply(1884): 643088 build_cell(317): 9826624 prepare_new_uac(524): 8112 prepare_new_uac(509): 10192 init_tm_stats_child(60): 5632 insert_tmcb(137): 136 init_tmcb_lists(74): 16 init_tmcb_lists(72): 16 init_hash_table(467): 2097152 Total: 14540768 } Module: usrloc { new_urecord(65): 136 new_ucontact(98): 1096 new_urecord(58): 288 shm_str_dup(723): 1200 build_stat_name(51): 64 new_udomain(93): 40960 new_udomain(86): 48 new_dlist(573): 16 new_dlist(565): 32 register_ulcb(94): 32 init_ulcb_list(45): 16 lock_set_alloc(70): 4112 Total: 48000 } Module: tmx { tmx_check_pretran(250): 864 tmx_check_pretran(271): 1216 tmx_init_pretran_table(90): 256 Total: 2336 } Module: sl { init_sl_stats_child(125): 4224 sl_startup(83): 8 init_sl_stats(110): 8 Total: 4240 } Module: carrierroute { rule_fixup_recursor(584): 8 shm_str_dup(723): 56 add_route_rule(74): 152 add_route_flags(225): 48 create_domain_data(83): 32 create_carrier_data(59): 8 create_carrier_data(50): 64 load_route_data_db(295): 8 load_domain_map(182): 48 load_domain_map(171): 24 load_carrier_map(126): 48 load_carrier_map(115): 24 reload_route_data(172): 64 init_route_data(74): 8 Total: 592 } Module: dispatcher { reindex_dests(600): 1008 add_dest2list(350): 168 add_dest2list(324): 4200 init_data(204): 16 init_data(195): 16 mod_init(309): 8 mod_init(307): 8 ds_ping_active_init(102): 8 Total: 5432 } Module: db_text { dbt_init_cache(81): 256 dbt_init_cache(69): 8 dbt_init_cache(54): 8 Total: 272 } The result of command kamctl shmem is: shmem:fragments = 6353 shmem:free_size = 406208 shmem:max_used_size = 8464105472 shmem:real_used_size = 8463699264 shmem:total_size = 8464105472 shmem:used_size = 5190698208 The server has 8G of shared memory allocated, and the issue happens more or less after 2 days running tests.

Kamailio blocked when using with Radius accounting when connection is lost with the database.
by Mx R 06 Jul '16

06 Jul '16

Hi there. I have the following scheme. 1. SIP server is running kamailio with module "acc", radiusclient-ng and freeradius. 2. DB server with MSSQL. The problem is the following, if the connection is lost with the database, no one can make calls. Even after the connection to the database is restored. We have to restart the radius and kamailio. And only after that can make calls. Kamailio logs rc_send_server: no reply from RADIUS server localhost: 1813 ERROR: acc [acc.c: 720]: acc_rad_request (): radius-ing failed Radius logs. Error: rlm_sql_unixodbc: SQL down 08S01 [unixODBC] [FreeTDS] [SQL Server] Write to the server failed Below are links to a similar problem. http://lists.opensips.org/pipermail/users/2012-March/021100.html http://lists.opensips.org/pipermail/users/2012-March/021102.html http://lists.opensips.org/pipermail/users/2012-March/021105.html http://lists.opensips.org/pipermail/users/2012-March/021128.html

Simple Kamailio configuration for Asterisk load balancing?
by Tickling Contest 06 Jul '16

06 Jul '16

Hello, I am beginning to front my Asterisk cluster with Kamailio and so far my biggest issue is the complete lack of quick-start-like documentation for this. Is there any place I can get a very simple HA configuration (telling me where the config files are, for starters, is a good thing) for Kamailio with the following features: (a) Support an arbitrarily large number of Asterisk servers (say, upto 10). (b) Offload SIP registration to a realtime/mysql DB used by the PBXs. Please also let me know if I should have to change my Asterisk PBX config in any way for this to happen. On a very related note, while I appreciate the fact that you need to _really_ understand SIP to configure Kamailio, it should be possible to get this setup by just running a script or GUI. It is difficult to find information on how to load balance multiple PBXs behind Kamailio. Thanks!

[rtprpoxy LB]
by Noriyuki Hayashi 06 Jul '16

06 Jul '16

Hi, Thank you for be used great KAMAILIO. Regarding rtpproxy LB. I configured as below. modparam("rtpproxy", "rtpproxy_sock", "udp:192.168.1.136:7722") modparam("rtpproxy", "rtpproxy_sock", "udp:192.168.1.137:7722") modparam("rtpproxy", "rtpproxy_sock", "udp:192.168.1.138:7722") modparam("rtpproxy", "rtpproxy_disable_tout", 20) modparam("rtpproxy", "rtpproxy_tout", 2) modparam("rtpproxy", "rtpproxy_retr", 2) I could not restart kamailio when one rtpproxy server is down. Does anyone tell this solution by the parameter or somthing ? I am looking forward from anyone. Thank you so much. Noriyuki Hayashi

I use a seperate machine for voicemail but I see no problem with other uses (I used to use it for playback of messages and transcoding ebtween incompatible endpoints). By using the prefixes in kamailio to the username in $ru I have in the extensions.conf: exten => _tovm-.,1,NoOp(leave voicemail) exten => _tovm-.,n,Answer() exten => _tovm-.,n,Set(CHANNEL(language)=nl) exten => _tovm-.,n,Voicemail(${EXTEN:5},us) exten => _tovm-.,n,Playback(Goodbye) exten => _tovm-.,n,Hangup() exten => _getvm-.,1,NoOp(read voicemail) exten => _getvm-.,n,Set(CHANNEL(language)=nl) exten => _getvm-.,n,VoicemailMain(${EXTEN:6}) exten => _getvm-.,n,Hangup() > The other question is that i actually though that you need asterisk to > have users configured in sipusers realtime table to associate their > mailboxes, which i dont have since those users are stored in the > subscriber table of kamailio.

So yes I have a realtime sip users list (with host=dynamic,type=friend,insecure=port,invite, name/mailbox the kamailio username, no password (this machine is not directly accessible from outside)) You might not be able to have endpoints able to subscribe to notifications due to this. I baked something inspired by: http://saevolgo.blogspot.nl/2012/07/asterisk-behind-kamailio-voicemail-mwi.… that appears to work for me.

dispatcher module not fetching attrs col from DB
by Jayesh Nambiar 05 Jul '16

05 Jul '16

Hi, I'm trying to use the dispatcher module with algo 9 for weighted distribution. I have a column attrs in the dispatcher table with value in the format "weight=90" for my destination addresses. But somehow the ds_list command always shows attrs as blank. I checked that kamailio doesn't fetch the attrs column at all; neither while starting up nor while calling ds_reload. This is the query that kamailio sends to my DB while starting up or calling the fifo ds_reload: select `setid`,`destination`,`flags`,`priority` from `dispatcher` I dont even see an attr column modparam in the documentation although kamailio didnt throw an error when I defined attr_col modparam for dispatcher module. Is there a different way to tell kamailio to fetch the attrs from the DB?? I'm using the 4.4.1 version. Thanks for any suggestion or pointers to solve this. - Jayesh

[SR-USERS] Kamailio issues with Asterisk Voicemail
by TEG AMJG 05 Jul '16

05 Jul '16

Dear list: I am quite new to Kamailio and i am really struggling to get some answer to some questions i have been trying to get answers by reading documentation and other questions or solutions around internet. Even though i am integrating Kamailio with two Asterisk boxes with the module dispatcher, i didnt follow the quite popular guide of Asterisk Kamailio Realtime Integration ( http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb). The reason why i didnt is that it actually behaved weird since i wanted Kamailio to be a stateful proxy and also wanted Kamailio to act as a Registrar Server and Location Server using subscriber and location tables of kamailio database, keeping both Asterisk strictly as Media Servers. Also i have been able to solve some NAT Traversal issues using RTPProxy and not using those Asterisk boxes with their nat or qualify parameters to solve NAT issues. Most of my solution started following this guide ( http://saevolgo.blogspot.com/2013/08/rtpproxy-revisited-kamailio-40.html) which let me handle registration and location with Kamailio and also changed it putting kamailio behind NAT. Now to the real question, is there anyway to include Asterisk voicemail functionality with the solution I already mentioned? the question is because, as I far as I know, Asterisk needs to associate mailboxes to its users. So i believe that i have to practically change most of my solution and find a way to make Kamailio register and locate users with the Realtime integration of Asterisk and map the registration accordingly to the table fields. But it destroys most of my NAT and register solution since i also configured one of the private IPs as a peer in Asterisk sort of like in that guide [Kamailio] type=friend host=192.168.1.244 port=5060 disallow=all allow=gsm allow=g729 allow=alaw allow=ulaw Sorry for making the question so long and to be quite ignorant with some of the concepts involving Kamailio with Asterisk Thanks Alejandro

Increase diversion counter
by Igor Potjevlesch 05 Jul '16

05 Jul '16

Hello, I'm looking for the best way to increase the Diversion counter. If my Kamailio is the first to generate a call forward I can manage this with static value into suffix params. But, if the Diversion counter is already set, I don't see how to handle this properly. Someone has already work on this? Regards, Igor.
