Hi,
We have been experiencing similar problem that I traced to print under windows. It seems that by changing the driver (in my case from 6P to HP III) almost stopped the trouble. I noticed two posting on news that also claimed cures for the dreaded page fault. So far it appears the drivers have a memory leak that cause most of the trouble. We still get the error about once a week so I'm still checking into the problem. I hope this helps.
