Online Engine Aborting -- Help!

We are experiencing a problem with the Online engine shuuting itself down. We see the following in the online.log: 4:30:17 Lock table overflow - user id 110, process id 23526 04:30:17 Lock table overflow - user id 110, process id 23526 04:30:22 Lock table overflow - user id 110, process id 23526 04:30:22 Lock table overflow - user id 110, process id 23526 04:30:27 Lock table overflow - user id 110, process id 23526 04:30:27 Lock table overflow - user id 110, process id 23526 04:30:32 Lock table overflow - user id 110, process id 23526 04:30:32 Lock table overflow - user id 110, process id 23526 04:30:37 Lock table overflow - user id 110, process id 23526 04:30:37 Lock table overflow - user id 110, process id 23526 04:30:56 Process Aborted Abnormally: pid=24710 user=1010 us=4040275c flags=1 04:30:56 Process Aborted Abnormally (latch): pid=24710 user=1010 flags=1 04:30:56 INFORMIX-OnLine entering ABORT mode!!! 04:30:56 -- Online Aborting -- us=40401b8c, pid=16995, uid=109 Tue Mar 1 04:40:59 1994 04:40:59 INFORMIX-OnLine Initialized -- Shared Memory Initialized 04:40:59 Physical Recovery Started 04:40:59 Checkpoint Completed 04:40:59 Physical Recovery Complete: 0 Pages Restored 04:40:59 Logical Recovery Complete: 0 Committed, 0 Rolled Back 04:40:59 Dropping temporary partition 1000006, recovering 8 pages. 04:41:01 Quiescent Mode 04:41:04 On-Line Mode 04:46:25 Checkpoint Completed 04:59:42 Checkpoint Completed 05:00:22 Checkpoint Completed The Lock table overflows actually started at 3:50 AM. Informix claims that the process aborting abnormally was because a process was killed. I don't buy this since users do not have Unix level access.
