I have Coda installed as a client on a FreeBSD 4.2 system:
FreeBSD Socrates.i-pi.com 4.2-BETA FreeBSD 4.2-BETA #0: Sat Nov 18 21:11:03 MST 2000     root_at_Socrates.i-pi.com:/usr/src/sys/compile/SOCRATES  i386
The server is another FreeBSD 4.2 system.

When I stress the system, for example by doing a hoard walk, or a find
something like:
find . -exec grep foo {} /dev/null \;
the client will become hung.  Trying to do anything else will normally
result in the machine dying with the message:
panic: vrele: negative ref count

Comments on how to solve this?
