[jira] [Commented] (TRAFODION-2314) MXOSRVR sometimes exit
abnormally with NAMutex assert
[ https://issues.apache.org/jira/browse/TRAFODION-2314?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15860492#comment-15860492 ]

[TRAFODION-2314] MXOSRVR sometimes exits abnormally with NAMutex assert
Fixes as suggested by @selvaganesang and @sandhyasun
We were hitting the code to make heap thread safe repeatedly while running
jdbc and phoenix tests.
PROCESS_LOB flag was being set incorrectly in some cases.
Unlocking a mutex owned by a different thread lead to the assertion.
This could also result in heap corruption.
