I am hoping someone can help me here.

I woke up this morning to 13 servers abended, all at approx. the same time,
all with "ERROR: Critical sectioning prevents requested FATFS operation"
on the screen. See TID 10099285. So here is a sample of the first of
approx. 15 abend log entries before one of the servers went off line. The
logs I have looked at on each server are very similar to what I paste
below. They are NW65SP6, eDir 881, all running same services for a school
district. Arcserve was running jobs on these servers. 2 of the servers
actually finished before the abend, so I have eliminated CA, for now.
Running NAV, but not pushing auto updates. There are 13 other servers in
the tree that were unaffected, business as normal.

I have not included the modules list. If you want to see them, let me know.

Thanks for any help you can provide.
