Our fileserver/router has had the same problem!  Typically, we get
crashes when someone sends a large print job, often one with a large
bitmapped graphic.  I've had a tough time finding someone at apple to
listen as our N&C answerline subscription ran out long ago (although
Stacy there has been extremely helpful, I can't really bug her
further).  Here's a sketch of our setup:

IIci with 8Mb memory, 1-bit video card, ethertalk card (Rev L)
A pile of hard disks (4 apple 80's and 2 FWB 600's and an FWB 300)
System 6.0.5
AppleShare File Server (2.0.1)
AppleShare Print Server (2.0, spools 5 printers)
Apple Internet Router (2.0)
QuickMail Mail Center (2.2.1)
DiskExpress II
localtalk cabling + thinwire ethertalk (used for IP data too)
Phase 2 only
GatorBox acting as backup router

We've tried NUMEROUS things to make the machine not crash, including:
increasing the system heap, removing software/inits, using a IIfx SCSI
terminator, changing mouse and keyboard, removing some disks, and even
changing the network numbers.  The only thing that seems to keep the
machine running is removing the router.

Our solution is to disable the router and buy an Ether*Route box for
$500.  We've tried for close to a year to correct the problem and
basically have given up!  

If anyone from Apple is reading this message and is interested in
trying to debug this problem, I'm willing to help in any way I can.
You can contact me via E-mail (Rob@goldilocks.lcs.mit.edu) or
AppleLink (MIT.SLS).
