TMQUEUE processes for a specific queue space dies and fail to restart.
Using qmadmin to inspect the qspace fails ... cannot open the queue space.

Typically TMQUEUE crash stack trace would indicate it occurred during a dequeue. For example:

#1  0x00209dee in _qm_dequeue_action () from /mytuxedo/tuxedo12.
#2  0x00200ed6 in qm_action_scheduler () from /mytuxedo/tuxedo12.
#3  0x08048d6d in _tmrunserver ()
#4  0x003cd6eb in _tmstartserver () from /mytuxedo/tuxedo12.
#5  0x08048cb4 in main ()

 It would also show ULOG chksum erorrs leading up to the TMQUEUE crash:

192232.mymach!TMQUEUE.4305.4151577184.0: Q_CAT:1353: ERROR: dequeue - checksum failed on block 123456 of table myTable on config /myQspaceudl

  In one occurrence the TMQUEUE did not core dump but hung and consumed 100% CPU


 migrated to Tuxedo 12.1.3 on Red Hat Linux with GlusterFS
