For what its worth, I have a NetBSD v2.0_RC4 SPARC64 as a primary 
network router/firewall.  The hardware is a Sun Netra T1 with internal 
18GB SCSI disks and a mirrored RAID set.

We had some initial problems with Squid (we were trying to use it as a 
transparent proxy), but when Squid started to exhaust the RAM, and 
swapping started to occur the machine seemed to fall down.  It would 
respond to pings, but it was impossible to log on via SSH, or even the 
console.  We simply dropped Squid as it was new non-required 
functionality.  And it has run very well since.

Still to upgrade it to NetBSD v2.0 final.  But if it ain't broke don't 
fix it!
