We have TM1 Version 9.1 SP2 running on a 64 bit server with 128gb of Ram.
The following message appeared in the message log, and shortly after this, the server came down.
5656 WARN 2009-01-14 06:15:26,205 TM1.Lock Attempt to release lock on 0x0000000157A5C340(0x0000000157A5C210). No lock held.

The only log entries prior to this were 1 hour beforehand, relating to a TI process, which finished executing normally.
Does anyone have any suggestions on where to look.
Thanks in advance for your help.
Regards
Armand
