Hello List, I have been running a very stable Kamailio 1.4 install for over a year now with no downtime. From time to time I get a message from the OS telling me that task kamailio:xxxx blocked for more than 120 seconds and a dump into syslog. I recently setup Kamailio 3.01 and it's been running for around 3 weeks now. Purely testing at the moment, there is only 1 SIP registration and almost no activity most of the time. I was checking dmesg and: [269844.208011] INFO: task kamailio:28504 blocked for more than 120 seconds. [269844.208093] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.

[Kamailio-Users] fr_inv_timer in kam-3.0

by Andreas Granig

Hi, In the docs at http://kamailio.org/docs/modules/3.0.x/modules/tm.html#fr_inv_timer it says that fr_inv_timer_avp should be defined like this, without $ or $avp: modparam("tm", "fr_inv_timer_avp", "my_fr_inv_timer") In kam <= 1.5 I did it like that: modparam("tm", "fr_inv_timer_avp", "$avp(s:callee_fr_inv_timer)") which doesn't give me an error on startup with kam-3.0 either, but the timer doesn't get fired (I use seconds for that as noted in the docs). If I change it to modparam("tm", "fr_inv_timer_avp", "callee_fr_inv_timer") then I get the error "malformed or non AVP callee_fr_inv_timer AVP definition", same with setting it to "s:callee_fr_inv_timer". Anyhow, it seems to be deprecated anyways, so I'm looking to get t_set_fr() working. I'm just curious how I can use a var or AVP loaded from DB to set the value on-the-fly? t_set_fr(...) seems to allow only constants to be set. Couldn't find anything in the docs regarding that one. Thanks, Andreas

[Kamailio-Users] drop in branch/onsend-route in kam-3.0

by Andreas Granig

Hi, Looks like behavior of drop has changed in Kamailio 3.0. Before, I was able to drop() a specific branch in branch_route depending on various checks. http://www.kamailio.org/dokuwiki/doku.php/core-cookbook:3.0.x#drop still says this is possible, http://kamailio.org/docs/modules/3.0.x/modules/tm.html#t_on_branch says it's not possible. So calling drop() in branch_route has no effect, and I have no idea how to mark a branch in branch_route to be dropped in onsend_route, because checking a bflag doesn't work there, and neither does checking $rU. Any ideas on how to accomplish dropping a specific branch? Andreas

[Kamailio-Users] Understanding memory-leaks by inspecting PKG/SHM memory status at shutdown

by Iñaki Baz Castillo

Hi, according to the wiki page: http://www.kamailio.org/dokuwiki/doku.php/troubleshooting:memory In order to detect a possible memory leak (in PGK or SHM) a good way is enabling memory debugging and shuting down the server, so: "the memory manager will dump the memory status. Normally most of the memory is cleaned during shutdown. If there is memory leak, it should be visible as not-freed memory." But I would like to know how exactly to detect if there is a memoty leak by inspecting the SHM/PKG status, something like this: ----------------------------------------------------------------------------------------------------------------------------- [32715]: Memory status (pkg): [32715]: fm_status (0x701a40): [32715]: heap size= 16777216 [32715]: used= 189696, used+overhead=247392, free=16529824 [32715]: max used (+overhead)= 247392 [32715]: dumping free list: [32715]: hash = 1 fragments no.: 1, unused: 0#012#011#011 bucket size: 8 - 8 (first 8) [32715]: hash = 2058 fragments no.: 1, unused: 0#012#011#011 bucket size: 8388608 - 16777216 (first 16530136) [32715]: TOTAL: 2 free fragments = 16530144 free bytes [32678]: Memory status (shm): [32678]: fm_status (0x7fa57921c000): [32678]: heap size= 67108864 [32678]: used= 16, used+overhead=35872, free=67072992 [32678]: max used (+overhead)= 2821064 [32678]: dumping free list: [32678]: hash = 1 fragments no.: 45, unused: 0#012#011#011 bucket size: 8 - 8 (first 8) [32678]: hash = 2 fragments no.: 4, unused: 0#012#011#011 bucket size: 16 - 16 (first 16) [32678]: hash = 3 fragments no.: 16, unused: 0#012#011#011 bucket size: 24 - 24 (first 24) [32678]: hash = 4 fragments no.: 2, unused: 0#012#011#011 bucket size: 32 - 32 (first 32) [32678]: hash = 5 fragments no.: 1, unused: 0#012#011#011 bucket size: 40 - 40 (first 40) [32678]: hash = 6 fragments no.: 1, unused: 0#012#011#011 bucket size: 48 - 48 (first 48) [32678]: hash = 7 fragments no.: 39, unused: 0#012#011#011 bucket size: 56 - 56 (first 56) [32678]: hash = 8 fragments no.: 1, unused: 0#012#011#011 bucket size: 64 - 64 (first 64) [32678]: hash = 9 fragments no.: 1, unused: 0#012#011#011 bucket size: 72 - 72 (first 72) [32678]: hash = 10 fragments no.: 2, unused: 0#012#011#011 bucket size: 80 - 80 (first 80) [32678]: hash = 15 fragments no.: 1, unused: 0#012#011#011 bucket size: 120 - 120 (first 120) [32678]: hash = 25 fragments no.: 1, unused: 0#012#011#011 bucket size: 200 - 200 (first 200) [32678]: hash = 40 fragments no.: 5, unused: 0#012#011#011 bucket size: 320 - 320 (first 320) [32678]: hash = 112 fragments no.: 1, unused: 0#012#011#011 bucket size: 896 - 896 (first 896) [32678]: hash = 128 fragments no.: 4, unused: 0#012#011#011 bucket size: 1024 - 1024 (first 1024) [32678]: hash = 129 fragments no.: 2, unused: 0#012#011#011 bucket size: 1032 - 1032 (first 1032) [32678]: hash = 224 fragments no.: 1, unused: 0#012#011#011 bucket size: 1792 - 1792 (first 1792) [32678]: hash = 258 fragments no.: 3, unused: 0#012#011#011 bucket size: 2064 - 2064 (first 2064) [32678]: hash = 473 fragments no.: 1, unused: 0#012#011#011 bucket size: 3784 - 3784 (first 3784) [32678]: hash = 1026 fragments no.: 1, unused: 0#012#011#011 bucket size: 8208 - 8208 (first 8208) [32678]: hash = 2049 fragments no.: 2, unused: 0#012#011#011 bucket size: 16384 - 32768 (first 16512) [32678]: hash = 2051 fragments no.: 1, unused: 0#012#011#011 bucket size: 65536 - 131072 (first 98336) [32678]: hash = 2056 fragments no.: 1, unused: 0#012#011#011 bucket size: 2097152 - 4194304 (first 2621440) [32678]: hash = 2060 fragments no.: 1, unused: 0#012#011#011 bucket size: 33554432 - 67108864 (first 64287800) [32678]: TOTAL: 137 free fragments = 67072992 free bytes ----------------------------------------------------------------------------------------------------------------------------- This is, how should look this SHM/PKG status example (after shutdown) in case there is a memory leak? how to detect not-freed memory?

Hello, I know some of devels are still in Easter vacation, but I hope we can get together soon on irc to sketch the plan for 3.1 release. I propose next week, Wednesday, April 14, 15:00UTC, on #sip-router channel hosted by irc.freenode.net If you are a developer and want to participate, please announce. If it is not possible to attend for major contributors, we can look for another date (eventually start a pool to see the day were most of us are available).

[Serusers] ReTransmission of CANCELs on 0.9.7

by rupert.organ＠bt.com

Hi All, Has anyone come up against an issue on 0.9.6 / 0.9.7 whereby a SIP App Server, delivers a CANCEL to the SER. The SER proxies the CANCELs to all the forked endpoints. At the same time it sends "200 Cancelling" back to the SIP App server...(this suppresses CANCEL retransmission from the SIP App server). If one of the CANCELs from the SER to the SIP UA gets lost....the phone keeps ringing. There is no CANCEL retransmission on the SER !!! There is CANCEL retransmission on the SIP App, but when it sends SER replies "no pending branches" Ideally want the SER do CANCEL retransmissions. I understand the timers were rewritten in 0.10.x but this is not hardened version like 0.9.6....any suggestions? Thanks in advance Rupert

[Kamailio-Users] merging users mailing lists

by Daniel-Constantin Mierla

Hello, I propose to merge the users mailing lists, most of the traffic these days is about 3.0 and even there are 2 stables branches now, they are sync'ed, so same code more or less. For 3.1 will be one stable branch, falvor selection will be only a matter of make command. Lately common useful topics are discussed on those different mailing lists, notifications and knowledge base building require cross-posting, lot of overhead imo. Any other opinion? Like with devel mailing lists, existing email addresses for users ML can still be used, just that end on same ML. Natural choice will be to have users@kamailio and serusers@iptel to be directed to sr-users(a)lists.sip-router.org Cheers, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/

Hi all! For easy editing kamailio configuration files I developed a syntax highlighting scheme for mc. Preview The scheme includes basic syntactic structures of Kamailio 1.5, all constants, variables, operators and standart core functions. To install it, download the file kamailio.syntax from attachment and copy it to /usr/share/mc/syntax (for Debian Etch) Next, add to the file /usr/share/mc/syntax/Syntax including: file ..\*\\.cfg$ Kamailio\sconfig include kamailio.syntax Thats all, I hope its helps someone ;) -- Shpinev Konstantin mailto:kks_mail@inbox.ru

Re: [Kamailio-Users] Odd Behaviour with Kamailio + TLS

Yes, i had installed self signed certificates via IE. Bria shows it and validates them during registration process, its the call initiation where it creates problem.
