Error: -458 Long transaction aborted.

Hi Folks, We really need a help here from you, experienced DBAs. We have ODS 5.0.2 server and we are receiving error# 458 on somewhat long transaction. During such transcations, I have been monitoring the log files and only 6-8 out of 16 are filled up and we are getting this nasty message. I also monitored the available lock but it is also not touching limit too. Is something I am missing?? Any help greatly appreciated. Thanks/Yogesh Error: -458 Long transaction aborted. The database server (probably OnLine or INFORMIX-OnLine for NetWare) ran out of log space in which to record this transaction. A transaction that is not fully recorded cannot be rolled back, so to preserve database integrity, the operating system ended the transaction and rolled it back automatically. All changes made since the start of the transaction have been removed. Terminate the application and replan it so that it modifies fewer rows per transaction. Alternatively, contact the OnLine administrator to discuss having the number or the size of the logical logs increased. Be prepared to talk about the number of rows being updated or inserted and the size of each row.
