When we first set ours up, we had the scan servers deregistering because of
network errors due to speed/duplex mismatches. (Seems that no matter how
often I tell everyone never use auto-negotiate it still keeps happening...)
It's definitely worth double-checking the port settings and switch settings
of all the systems involved just in case.
In our case when the client deregistered, fixing the network problem didn't
get the client to re-register, but rebooting the scan server fixed it.
It's not clear to me why the loss of a scan server would increase CPU usage
on the filer side. The filer is just sending scan requests to the scan
servers. With only one server up it's still sending the same number of
requests. Especially with those requests being non-blocking that doesn't
make sense to me. In fact, it makes me more suspicious of a network issue.
Certain types of network problems can cause significant cpu usage.

David,
Yes, the virus scanner is on the same segment using Gig NIC. Also,
mandatory scanning is OFF on the Filer.
Thanks,

Is the virus scanner on the same segment as the filers?
Also, what kind of network card are you using in the Virus Scanning machine.

Hi Toasters,
I have two NT servers using TrendMicro ServerProtect as a virus scanner for
F760 running ONTAP 6.3.1R1. Sometimes one of the virus scanner server did
not registered. I restarted the TrendMicro NT service and it registered
with the Filer again. The only change lately was to update the WINS Server
on the Filer.
Apparently, the Filer was consistently at 100% CPU usage. But after the
second virus scanner registered to the Filer, the CPU was reduce to 50%.
Any ideas why the virus scanner got 'de-registered' and why would this cause
high CPU on the Filer?
Error:
CIFS: Virus scanner 10.10.10.10 attempted to register but had insufficient
privilege. Tue Apr 1 20:45:02 CST last message repeated 5 times
thanks,
Marcus Bui
