[asterisk-bugs] [JIRA] (ASTERISK-27591) Frack errors in stasis.c and memory leakage

[Corey Farrell (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-27591?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=241623#comment-241623 ] 

Corey Farrell commented on ASTERISK-27591:
------------------------------------------

If possible please also collect a reference debug log \[1\].  You would need to do a more limited test, thousands of calls would create a log so large that the refcounter.py script would run out of memory processing the results.  Please also specify the exact version you test with (and if you added any patches).  I have recently done some work on stasis which I'm pretty sure you are not running but want to confirm.
