I have a nas running Windows server 2008 standard sp2 (x86) and in the past few days it has started crashing whenever there was more then only light network traffic going on.
It happens when: - Downloading torrents (both in µtorrent and vuze) - Copying files to and from the nas using teracopy
The nas has 4 disks, which are not in a raid configuration but are encrypted using truecrypt. First I thought one of the disks went bad, so I checked all of them using hdtune, but no bad sectors were found. It seems to be quite mysterious problem. With only light traffic, just watching some movies off it etc,... it runs perfectly fine.
SysInternals Process Explorer will help identify your problem..
