[asterisk-bugs] [JIRA] (ASTERISK-23348) Allocation failure in ast_unreal_new_channels causes core dump

[Corey Farrell (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-23348?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=215575#comment-215575 ] 

Corey Farrell commented on ASTERISK-23348:
------------------------------------------

You are right, {{ast_channel_internal_alertpipe_init}} failed.  I found this by adding abort() to the error conditions of {{__ast_channel_alloc_ap}}.  Also, ulimit -n is 1024.

As for the limit, I'm not sure how many channels are being created but the backtrace only shows 225 threads.  I would guess this is due to my using timerfd, and the fix for ASTERISK-16783 (extra fd's from ast_channel_internal_alertpipe_init).
