Fault Bucket error from Outlook--Office XP Professional

[HB]

I keep getting "fault bucket ......" frequently from the
Outlook program. The .... are basically system generated
numbers. I have Office XP Professional with SP2 applied.
Microsoft Knowledge Base does not have anything that
resembles my error. They have a lot of articles
about "invalid page fault" but my error is more about
fault bucket.

Please let me know if somebody knows how to fix this
error.

Thanks
