| Description: | Asterisk segfaults randomly with a large number of SIP registrations. This issue was not present in 1.8.23.1 and has appeared in later versions.
The issue looks related to parsing of the digest in sip packets Thread 30 (Thread 36177): #0 0x00002b900ca36343 in ?? () #1 0x000000000053a0c0 in tdd_generate (tdd=0x7e53c0, buf=0x2b9030000938 "\260\271nl\223+", str=<value optimized out>) at tdd.c:355 #2 0x0000000000000003 in ??

| Comments: | By: Matt Jordan (mjordan) 2014-03-18 07:08:02.596-0500 I'm not sure this is going to be related to digest parsing, since the little bit that survived in the backtrace is in a tdd_generate. Regardless, we'll need the full unoptimized backtrace to figure out what is going on. Please compile Asterisk with DONT_OPTIMIZE and BETTER_BACKTRACES - that should produce a good backtrace. By: Ross Beer (rossbeer) 2014-03-18 20:03:57.904-0500 This issues appears to be a threadlock, when this happens the SIP channel does not process any further sip packets, Any packets being send time out. By: Ross Beer (rossbeer) 2014-03-24 06:38:12.249-0500 The SIP channel stopped again and stopped accepting registration attempts By: Matt Jordan (mjordan) 2014-03-25 10:02:16.835-0500 Is your dialplan using any switch statements, or using {{pbx_realtime}}? By: Ross Beer (rossbeer) 2014-03-25 10:21:58.602-0500 Both switch statements and pbx_realtime are in use. By: Rusty Newton (rnewton) 2014-04-14 08:56:08.141-0500 Closing out as I believe this is most likely a duplicate of ASTERISK-21228 Watch that issue for any further updates. | ||||
