| Description: | After working for a couple of minutes on a server with small IAX load (couple of calls per minute) Asterisk runs out of idle IAX2 threads. Problem can be easily repeated - the server works for a couple of minutes then stops responding to IAX. chan_iax2.c: Out of idle IAX2 threads for I/O, pausing! ... IAX2 Thread Information Idle Threads:LI> Active Threads:> Thread D99: state=2, update=61, actions=2, func ='socket_process' Thread D98: state=2, update=61, actions=3, func ='socket_process' Thread D97: state=2, update=61, actions=11, func ='socket_process' ... Thread P6: state=2, update=84, actions=7045, func ='socket_process' Thread P5: state=2, update=85, actions=7017, func ='socket_process' Thread P8: state=2, update=85, actions=7010, func ='socket_process' Thread P1: state=2, update=86, actions=7016, func ='socket_process' Dynamic Threads: 110 of 10 threads accounted for with 0 dynamic threads ****** ADDITIONAL INFORMATION ****** I have also compiled asterisk with 500 (instead of 100) dynamic threads - server worked a bit longer but eventually IAX2 blocked - out of idle threads: Thread P5: state=2, update=23935, actions=144933, func ='socket_process' Thread P7: state=2, update=23935, actions=144933, func ='expire_registry' Thread P6: state=2, update=23935, actions=144878, func ='expire_registry' Thread P4: state=2, update=23935, actions=144920, func ='socket_process' Thread P10: state=2, update=23935, actions=144770, func ='expire_registry' Dynamic Threads: 510 of 10 threads accounted for with 0 dynamic threads Fedora Core (2.6.5-1.358smp) Dual Xeon (64 bit) | ||
| Comments: | By: Dawid M (dmielnik) 2006-10-17 04:22:45 I seem to have put the wrong category - its not really IAX Database support By: Joshua C. Colp (jcolp) 2006-10-17 15:50:21 Can you please use gdb to acquire a backtrace? It will allow me to see where every thread is hanging, or would it be possible to arrange access so I could try to diagnose it? Thanks. By: Dawid M (dmielnik) 2006-10-17 17:45:54 ok - attached the gdb back traces please contect me - dmielnik (at) voiceware.pl if you would still want to arrange access to the server. By: Joshua C. Colp (jcolp) 2006-10-18 12:38:37 Is this an unoptimized build? By: Dawid M (dmielnik) 2006-10-18 12:48:52 No - this is an optimized build. I am not sure but I think I have tried compiling with DONT_OPTIMIZE with the same effect. By: Joshua C. Colp (jcolp) 2006-10-18 12:50:22 The issue may still reoccur with an unoptimized build but in order to accurately track it down from a backtrace it needs to be unoptimized. By: Dawid M (dmielnik) 2006-10-18 12:53:44 ok - I will provide you with backtraces of the deadlock for an unoptimazed build in about 20 minutes. By: Dawid M (dmielnik) 2006-10-18 14:00:50 ok - uploaded backtrace for non optimized build By: Joshua C. Colp (jcolp) 2006-11-02 10:34:20.000-0600 This issue should be resolved in the latest chan_iax2 commit I did. Give it a go. If not please reopen. | ||
