We have a similar setup at work and the reason for the dropout is not easily known. If you contact your TrendMicro sales/tech rep. s/he will most likely ask you to run a debug and from that the possibility of finding the fault is higher.

If you have mandatory scanning set on your filer, (see your vscan options) then ALL files must be scanned before they leave the filer. I am guessing that when the first go down, the load of the other AV box has to take the load of the one that went down. And because of the files waiting to be processed, this can increase the load of your CPU as well.

When deploying dual AV box scenario, it is best to overspec the box so that in the event of failure of one, you know the other can handle the load of two. There is a way to bypass this though -- you can turn off mandatory scanning on the filer, but use with caution!

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,
