[asterisk-bugs] [JIRA] (ASTERISK-21305) Segfault recording Meetme

[Pedro Peña (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-21305?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=204697#comment-204697 ] 

Pedro Peña commented on ASTERISK-21305:
---------------------------------------

Really this test reproduces crashes in a production system at a rate of 4 - 16 hours, just that much faster. Note that disabling record of meetme the crash not occurs (the same in production). In production the backtraces not are the same too, but always related with a hungup of a channel when the conference is being established.

I also observed that there is a corruption on the vars of the recording thread.

At the moment the only solution in production is to start record when the conference is established, not from the beginning (not using the 'r' param).
