[Zope] Conflict error

[Brian Sullivan]

Zope 2.9.4 (but also happens on Zope.2.9.1)
XP and Windows 2003

Often I see messages like the following in the event log:

2006-11-20T11:57:33 INFO ZPublisher.Conflict ConflictError at
/<***some location***> : database conflict error (oid 0x03a7, class
BTrees._OOBTree.OOBTree, serial this txn started with
0x0369ab934257a788 2006-11-20 16:51:15.549000, serial currently
committed 0x0369ab9975fb5b99 2006-11-20 16:57:27.652000) (122
conflicts (2 unresolved) since startup at Fri Nov 17 16:01:43 2006)

I am also seeing the server go into some sort hard crash (actually it
doesn't crash just seems to peg the cpu doing something) ...that seems
related. (but I am not totally sure). Sometimes it "magically"
recovers but more often than not I have to restart the service to get
some sense of normality.

What does this message mean -- should I be worried about it? Is it
related to my "crash"?
