I'm seeing some strange behavior on a 2.1.0 network.
I have a server that exports an nfs partition to 5 clients
every so often (daily) one client has all its nfsiod processes
go into diskwait on accessing files on the nfs partition.

rebooting that client temporarily clears the error

the server however also has troubles.  every so often
(weekly) it crashes on a page fault in the MALLOC macro
is some nfs code.

the only obvious potential souce of problems I can think of
is a memory upgrade done to the server a couple months back

it used to be 32mb ram/48 swap, but now its 64mb ram/48 swap
all this machine is doing is running a bunch of basic net daemons
(timed, rwhod) and nfs,  its not even running x-windows

any advice?
