Greetings
I have Promise 48TB RAID system connected to MacPro and CIFS mounted
to a Dell 1950 8-core running RedHat Enterprise 3. I was not so much
worried about security, but it did seem to perform better than NFS,
for instance. It has worked well up until now. We recently had to
migrate some large apps from the Mac to the linux box because a vendor
no longer supports the Mac which puts a lot of traffic through the
mount. Yesterday we starting seeing errors:

Have I reached the limits of CIFS capability? I've been poking around
the web trying to find a manual that describes these errors. Can
someone point me to a manual or tell me what the errors mean?
Thanks
