| Description: | Asterisk died with a Segmentation fault.
Analysing the core dump I presume this issue is related with Agent channel, because it happens (randomly) when an Agent is trying to transfer a call or is receiving a call from a SIP channel. It happens mainly when the Agent is trying to transfer the call to an extension (9990) wish is a survey system (AGI written in PHP)to qualify the Agent. It also happens when a SIP extensin tries to call an Agent. Its happens 2 to 5 times a day (today already happend twice). | ||||

By: Richard Mudgett (rmudgett) 2013-05-20 12:05:25.084-0500 The backtrace attached to the issue is showing a crash as the result of the AMI Redirect action. This appears to be a duplicate of: ASTERISK-21356 By: Rodrigo P. Telles (telles) 2013-05-20 13:00:28.936-0500 Looks like the patch solved the problem on 21356 and I see it was developed for v11.5.0. Does that fits on 1.8 LTS? Anything I can do to fix that on 1.8.21.0 or 1.8.22.0? Tks By: Matt Jordan (mjordan) 2013-05-20 13:57:38.890-0500 That patch was applied to the 1.8 branch as well, and is in 1.8.22.0. By: Rusty Newton (rnewton) 2013-05-21 18:06:31.595-0500 Please test with 1.8.22.0 and report back. Hit "Send Back" to alert us of your reply. By: Rodrigo P. Telles (telles) 2013-05-22 06:41:08.878-0500 Hi, I am running 1.8.22.0 since yesterday and the problem happend 6 times till now, so the patch did not solve the problem. Follows the backtrace of the last core dump. Tks By: Richard Mudgett (rmudgett) 2013-05-22 11:41:33.204-0500 [^jira_asterisk_21793_v1.8.patch] - Checks bridged pointer for NULL to avoid a crash. This patch will just prevent the crash. It looks like chan_agent is returning a NULL pointer when it probably should be returning a pointer to the channel the Agent channel is pretending to be. Please test and report back. By: Rodrigo P. Telles (telles) 2013-05-22 12:47:20.307-0500 I will apply the patch and see if it solves the problem. Tks Richard! By: Rodrigo P. Telles (telles) 2013-05-29 06:37:58.822-0500 Hello Richard! Your patch solved the problem :-) Asterisk does not died since than! I really appreciate your help. | ||||
