[jira] [Commented] (TS-2883) core dump in TSFetchCreate()
[ https://issues.apache.org/jira/browse/TS-2883?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14260172#comment-14260172 ]
Sudheer Vinukonda commented on TS-2883:
---------------------------------------
Fyi - TS-3083 reported a similar issue in v5.2.0 (also caused by double deletion of FetchSM). They are trying the patch attached here (with an optimization from [~yunkai] to replace the mutex with cas).
