[asterisk-bugs] [JIRA] (ASTERISK-27170) memory corruption probably related to operations involved into PickupChan

[nappsoft (JIRA)]

    [ https://issues.asterisk.org/jira/browse/ASTERISK-27170?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=238177#comment-238177 ] 

nappsoft commented on ASTERISK-27170:
-------------------------------------

Yesterday and today we have observed two more crashed in the live system, in both cases it happened again immediately after the call in which a PickupChan operation was involved had been hung up. => So this simply can't be a coincidence anymore. A pickup was involved into all observed crashes (7 during the last 16 days) since we started taking sip traces and as these operations happen in less than 1% of the calls (according to the number of calls per day and the pickups visible in the sip traces) it must have something to do with this operation...

> From time to time asterisk crashes when a component is trying to allocate memory. According to the sip traces this seem to happen mainly soon (sometimes some milliseconds, sometimes a few seconds) after a call in which a PickupChan operation was involved has been finished.
