TLS module not initialized in 4.3.3, worked in 4.1.5
by Sebastian Damm 16 Nov '15

16 Nov '15

Hello, we just updated one kamailio server from 4.1.5 to 4.3.3, and although the config file is correct and kamailio starts up, it doesn't initialize TLS and says " tls support enabled, but no tls engine available (forgot to load the tls module?)" In the log I see: Old shutdown (last lines): Nov 13 11:44:38 lasola /usr/sbin/kamailio[15890]: DEBUG: <core> [mem/shm_mem.c:235]: shm_mem_destroy(): destroying the shared memory lock Nov 13 11:44:41 lasola /usr/sbin/kamailio[14818]: ERROR: <core> [tcp_read.c:271]: tcp_read_data(): error reading: Connection reset by peer (104) Nov 13 11:44:41 lasola /usr/sbin/kamailio[14818]: ERROR: <core> [tcp_read.c:1296]: tcp_read_req(): ERROR: tcp_read_req: error reading New startup (first lines): Nov 13 11:44:42 lasola /usr/sbin/kamailio[16113]: DEBUG: <core> [daemonize.c:583]: set_core_dump(): core dump limits set to 18446744073709551615 Nov 13 11:44:42 lasola /usr/sbin/kamailio[16113]: WARNING: <core> [main.c:2475]: main(): tls support enabled, but no tls engine available (forgot to load the tls module?)

In version 4.1.1, this config worked without a problem. Has anybody seen this before? the tls module is there and available, it doesn't say anything about "cannot load module", and it is only a warning message. I'm also wondering, why this message is the first after starting the server. From config I would expect that sl, tm and all the other modules should be initialized before tls. Best Regards, Sebastian

Detecting problems of kamailio under very high load
by aft 16 Nov '15

16 Nov '15

We have multiple kamailio servers with 4 cpu cores and 16G RAM. We use kamailio+rtpproxy as a outbound sip proxy. Usually there are many thousands of concurrent sip sessions of occurring there. Periodically sometimes it just stops serving request and spits out 5** replies. At that point we usually reload the kamailio daemon and things return back to normal. As we have a lot of servers, manually doing this is a pain in the neck. So We installed a homer/sipcapture on a separate server . And from there, we periodically scan for 500 msgs for a given time interval. If there are any, we then proceed to reload kamailio. I know its hell of an inefficient system to monitor. So I'm wondering, if there can be any more rational way to detect problems pre-emptively. any fifo/mi command which we could run to find out if the kamailio instance is hung up? Cheers Arif

Hello all, I installed kamailio on debian from kamailio's apt repository. Configured it with kamdbctl, started it up properly, no issues. I configured mysql also, worked properly.

Kamailio queues
by David Villasmil Govea 13 Nov '15

13 Nov '15

Hello Guys, I'm new to this list. I'm trying to setup a queue with 4.3.3 (x86_64/linux) and I see a couple of things i'm wondering about: - kamdbctl created the table "mohqueues" and the associated value in the "version" tables. Whereas kamailio uses "mohqueue" (no extra "s" at the end). - after fixing that, it finds the table, but when searching for the moh file, which i set as "/var/kamailio/MOH/test.8" on the mohqueue table, but kamailio can't find it: 0(61540) ERROR: mohqueue [mohq.c:390]: mod_init(): Unable to load rtpproxy_answer 0(61540) ERROR: <core> [sr_module.c:962]: init_mod(): Error while initializing module mohqueue (/usr/lib/x86_64-linux-gnu/kamailio/modules/mohqueue.so) ERROR: error while initializing modules ls -l /var/kamailio/MOH/test.8 -rw-rw-rw- 1 root root 166038 Jun 10 2009 /var/kamailio/MOH/test.8 Can anyone lend a hand? Thanks! David -- DVG -- Imagination is more important than knowledge Albert Einstein

Re: [SR-Users] Flaky & unstable RTP connections
by Infinicalls Infinicalls 13 Nov '15

13 Nov '15

Hi, I have started RTP with # ./rtpproxy -F -l localhost -s udp:*:7890 and when I issue #netstat -pln | grep rtpp I get, udp 0 0 0.0.0.0:7890 0.0.0.0:* 8759/rtpproxy I am using another similar instance of RTP also. Still my connection seems to be flaky. This doesn't occur always. I am not using dispatcher here. Simple rtpproxy with udp:rtp1 and udp:rtp2 in kamailio.cfg file. Is there anyway to tell if RTP is healthy other than making calls and finding out? Can somebody test it from your end? Or is this problem client specific? I am using microlite and sipper on windows. phone.infinicalls.com u:test;p:test123 u:trial;p:trial123 5060 regards Ganesh Kumar

Unable to find dialog
by Ryan Brindley 12 Nov '15

12 Nov '15

Hey community, Our current switch is being overloaded and when it does we're getting these 2 messages spammed in our logs: WARNING: dialog [dlg_handlers.c:1127]: dlg_onroute(): unable to find dialog for ACK with route param '35d.d2f1' [3411:7981] ERROR: tm [t_reply.c:1341]: t_should_relay_response(): ERROR: t_should_relay_response: status rewrite by UAS: stored: 503, received: 100 We're obviously working on not having the switch get so overloaded, but I'm also curious to understand why it can't find the dialogs. Is it a memory issue? Networking/dropping packets issue? I also imagine it's not as simple as a single overall answer either, but nevertheless I figured I'd reach out to the community and see if anyone has an understanding of what is happening and would be willing to take a few mins to explain. Thanks in advance, Ryan Brindley Software Development Officer Stratics Networks, Inc. 1.866.635.6918 x108
