Hi

First machine
	Pentium II 266mhz
	128meg RAM
	FreeBSD 2.2.5
	DPT RAID Cacheing Controller Card (SMART) - 64meg Cache RAM
	DPT RAID 5 Array (20gig, 16.4gig Useable)
	FreeBSD 2.2.5
	NFS Server
	
Second machine & Third machine
	Pentium II 266mhz
	128meg RAM
	FreeBSD 2.2.6
	NFS client

Every so often the first machine seems to lock up, it's generally
down to when I'm playing with something like quota's etc. but it 
has happened on it's own once or twice. Has anyone else experienced
similar? The system locks up and because the drive is exported and
mounted on many different machines those machines fall over as well.
It's bloody annoying :-/ I realise mounting the drive as soft on
the NFS client machines would stop /those/ falling over but I'd
prefer to stop it crashing all together. I'm having a hard time
getting the first machine to have an uptime in excess of 14days!

There's quite a bit of traffic going between the machines but
they are on their own switched 100mbps hub, the above machines
act as squid proxy servers with all the cache information 
stored on the array in seperate directories and linked
as a sibling hierarchy to a parent upstream from us.

Regards,

Jay Tribick
