This is an OS problem. There are notes on tuning the OS KAIO parameters in your release notes. Can't remember exactly where, but if you grep KAIO $INFORMIXDIR/release/*/*/*, you should find a similar error in the notes, with details of what to do. > Is this a fatal error? No. Basically it is a timeout message. Quite often you will get lots of these messages consecutively in the log as the retry also fails. The IO does complete though. You need to tune your kernel parameters. Cheers, -- Mark. +----------------------------------------------------------+-----------+ | Mark D.
