The log only > has a "ERROR: page cleaner # X has timed out" if the page cleaner times out, that means that it was trying to write to disk and couldn't. i have usually seen this associated with hardware problems. look in your system log and see if you are having lots of retries on writes to your disks, things like this. i have had the same thing before, although it was a while ago. that is all i remember is that we were having hardware problems. the only other real issue is that if the contention for your disks is so high that the queues are long enough that the page cleaners time out before they get their write request satisfied. use sar or iostat and look at the disks and see what kind of wait queues they have things like that. hope this helped. mickm ------------673325D547C2 Content-Transfer-Encoding: 7bit Content-Type: text/html; charset=us-ascii <HTML><BODY> <DT><BR> > Running Informix OnLine 5.03 (ancient, I know) and<BR> > I continually have page cleaners to go into (E)xit<BR> > state and NEVER COME BACK!<BR> > <BR> > Kinda new to Informix, and I'm not sure how to<BR> > figure out why this is happening.
