-------------------------------------------

Hello Benjamin, Asterisk was compiled with:
Build Options:               DONT_OPTIMIZE, COMPILE_DOUBLE, BETTER_BACKTRACES, OPTIONAL_API

The crashes occur at moment with moderate traffic (~30 calls). There is no error in the logs. The problems started when because of queue-problems we switched to pjsip. So there are two main items that are changed: queuing from ringall to leastcalled and from chan_sip to chan_pjsip. Now i donnot believe either of them is the real cause of the problems.
Now i am looking at the logfiles and i see a lot of:
[2019-03-15 21:57:00] ERROR[22319][C-00000012]: pbx_functions.c:610 ast_func_read: Function SIP_HEADER not registered
[2019-03-15 21:57:00] ERROR[22319][C-00000012]: pbx_functions.c:653 ast_func_read2: Function SIP_HEADER not registered
[2019-03-15 21:57:00] ERROR[22319][C-00000012]: res_pjsip_header_funcs.c:454 func_read_header: This function requires a PJSIP channel.
[2019-03-15 21:57:00] ERROR[22319][C-00000012]: res_pjsip_header_funcs.c:454 func_read_header: This function requires a PJSIP channel.

Surely this should not be there (dialplan problems probably), but i also donnot believe this can cause a segmentation fault in Asterisk.

The error in the logs that i am a little concerned about is:
[2019-03-15 21:56:59] WARNING[22306][C-00000012]: taskprocessor.c:895 taskprocessor_push: The 'subp:ast_channel_topic_all-000003fd' task processor queue reached 500 scheduled tasks again.
[2019-03-15 21:56:59] WARNING[22302][C-00000012]: taskprocessor.c:895 taskprocessor_push: The 'subm:ast_channel_topic_all-cached-000000ce' task processor queue reached 500 scheduled tasks again.

Not sure what these queues are and why they are filling up.
I really hope you can help me with this as this is actually a reinstalled PBX after the first one had exactly the same problems.

> The Asterisk process keeps producing a segmentation fault a few times a day. I have attached the coredump information of one of the segmentation faults.
