[asterisk-bugs] [JIRA] (ASTERISK-26219) segfault in ast_manager_build_channel_state_string_prefix

[Michel R. Vaillancourt (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-26219?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Michel R. Vaillancourt updated ASTERISK-26219:
----------------------------------------------

    Attachment: sept06segfault.full.log

Unfortunately, we did not have "verbose" enabled in our "messages" log file, so the only place that CLI output is being captured in any fashion is the "full" log file.

I've attached an extraction of the five minute window surrounding the crash.  I hope there is something valuable you can find in there.

We've changed out logger.conf to be capturing CLI at Verbose(3) for the next time around.
