Online Engine Aborting!!

I posted something last week which has still not been explained and has gotten worse. For the past 5 nights our engine has dhut itself down citing that a process has aborted abnormally as follows: ======================================================================= 03:23:45 Checkpoint Completed 03:25:29 Checkpoint Completed 03:30:14 Checkpoint Completed 03:30:40 Process Aborted Abnormally: pid=24697 user=110 us=4040224c flags=101 03:30:40 Process Aborted Abnormally (critical section): pid=24697 user=110 flags=101 03:30:40 INFORMIX-OnLine entering ABORT mode!!! 03:30:40 -- Online Aborting -- us=40401b8c, pid=20146, uid=109 ========================================================================= On my other post there were LOCK TABLE OVERFLOW statements from the engine before the abort. This has not been the case in the last several aborts. The most popular theory before was that the LOCKS parameter setting was too low. This is set to 30,000 now (pretty large). The engine has been aborting in the early morning 2-5 am. This is when it is most active. User 110 is an administrative account which starts up our systems daemon processes. This id is NOT always the owner of the process that gets aborted abnormally. Some other info on our configuration: ===================================== 2 databases both set to NO LOGGING rootdbs size - 13.5 MB 4 other dbspaces various sizes Logical Logs - 7 each 1MB each and all in rootdbs Physical Log - 1 and is 1MB in size in rootdbs Thanks for any help - please replay via email if possible, Bill ennis@ssd.comm.mot.com -- Bill Ennis ennis@ssd.comm.mot.com
