[asterisk-bugs] [JIRA] (ASTERISK-25374) Crash in cdr handle_dial_message where peer is null

[Scott Griepentrog (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-25374?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=227475#comment-227475 ] 

Scott Griepentrog commented on ASTERISK-25374:
----------------------------------------------

The test system in this case has only 1g ram and no swap, so an allocation failure of peer that was not immediately detected could be the culprit here.
