[asterisk-bugs] [JIRA] (ASTERISK-27300) Asterisk crashes randomly (FRACK!, chan_sip)

[Alex A. Welzl (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-27300?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=239670#comment-239670 ] 

Alex A. Welzl commented on ASTERISK-27300:
------------------------------------------

THX for the info.
What does "the peer goes away" mean?
The last documented crash happened during the night, so there was no reloading nor a high load on the system itself. I will enable debug logging and add requested details after the next crash.

> Asterisk crashes randomly (currently 1-2 times per week). Any idea if this is the same issue like ASTERISK-26699? If not, upgrading to another version makes no sense.
