Description:	Random segfaults on 1.4.17 every couple of days or so - nothing abnormal logged (debug 10/verbose 10). This is a moderately busy SIP-only PBX, with realtime (ODBC) queues and AMI in use. I'll attach a full backtrace (DONT_OPTIMIZE), slightly sanitized.

By: Stuart Henderson (stuarth) 2008-01-26 18:21:24.000-0600 SIGSEGV there too (different, though) - I've added backtrace to 0011386 By: Tilghman Lesher (tilghman) 2008-01-27 10:35:40.000-0600 Well, the patch from ASTERISK-10897 definitely fixed this problem; though you're seeing a bit of a different problem, still. By: Joshua C. Colp (jcolp) 2008-01-28 06:41:04.000-0600 The current underlying issue here (since the original has been solved) is actually 11811. Check there for progress.
