Package: asterisk
Version: 1:1.6.2.9-2+squeeze3
Severity: important
Hi,
At a customer, asterisk is crashing semi-randomly. I'm seeing this:
(gdb) where
#0 _sip_tcp_helper_thread (pvt=<value optimized out>, tcptls_session=0x0) at chan_sip.c:3200
#1 0x00000000004e47aa in dummy_start (data=<value optimized out>) at utils.c:967
#2 0x00007fc6c80218ba in start_thread () from /lib/libpthread.so.0
#3 0x00007fc6c8a5e02d in clone () from /lib/libc.so.6
#4 0x0000000000000000 in ?? ()
chan_sip.c:3200 contains the following:
3199> cleanup: │
3200> if (!tcptls_session->client && !authenticated) { │
3201> ast_atomic_fetchadd_int(&unauth_sessions, -1); │
3202> }
(gdb) p tcptls_session
$1 = (struct ast_tcptls_session_instance *) 0x0
Regards,
