Hello Experts

Having a hard time trying to track down the source of one of our servers intermittent freezing

What happens on the odd occasion (3 times last month, 1 time this month so far) is that the server completely 'locks up'

We have a 2 server site setup, so when it happens, we can connect to serverB and ping serverA

We cannot however connect to any resources on ServerA (ServerA runs exchange and some other file shares)

Its a Dell poweredge R710 server, so when I connect to the DRAC - the console responds to mouse, but not keyboard. The only remedy at this point is to restart the server

Once the server starts back up, there is a pysical 'gap' in the event logs. As in - when the server crashes until when the server is back up, there is a gap in all event logs (system, application, security etc)

The only thing that seems to be happening is a VSS start command

Log Name:      System
Source:        Service Control Manager
Date:          16/03/2012 7:15:01 AM
Event ID:      7036
Task Category: None
Level:         Information
Keywords:      Classic
User:          N/A
Computer:      ServerA
Description:
The Volume Shadow Copy service entered the running state.

Shadow copies are disabled via 'My computer' - however we do run shadow protect as a backup solution that runs on the hour (15 minutes past the hour) that backs up the server volumes to a NAS over gigabit network

It's only the odd occasion when the server locks up, but the symptoms are exactly the same

Vss admin list writers show all writers as stable, all system volumes are 0% fragmented, Dell drivers for the RAID controller are up to date

Any other ideas?
