Hi! I just made some load testing and came across a problem. In some cases with a high volume of calls ( > 40) all trying to start a connection asterisk sometimes crashed without any output. I only got a coredump when running it with asterisk -gvvvvvc (thanks to the hint from RoyK in IRC) but this shows, that the problem seems to be found somewhere in t1_timeout. This is what gdb says: (gdb) bt #0 0x40861cf6 in t1_timeout (arg=0x8180078) at chan_ss7.c:765 #1 0x08056528 in ast_sched_runq (con=0x8148990) at sched.c:373 #2 0x40869643 in monitor_main (data=0x0) at chan_ss7.c:3402 #3 0x40027e51 in pthread_start_thread () from /lib/libpthread.so.0 #4 0x401ef92a in clone () from /lib/libc.so.6 I have the two coredumps here, if someone needs them for a further analyses as my programming knowledge is not enough to figure this out.
