This is using a vanilla 2.4.13 Kernel on a dual processor PPro with
512MB of memory and a Mylex RAID array (DAC960).

Reiserfs works fine locally, but knfsd locks up at after about 15
minutes (300MB) of ``cp -a''. The nfs client is a 533MHz Alpha with
768MB of memory on a stock Redhat 7.1 distribution:
Linux sarg.ryerson.ca 2.4.3-12 #1 Mon Sep 3 16:21:08 EDT 2001 alpha unknown
sarg (the client) and fs (the server) are talking over a 100Mb
crossover cable, so fs was getting beaten pretty hard. I had a shell
running on fs and it was fine all the time. It also doesn't seem to
be bandwidth related because I ssh'ed across 4+GB earlier (to another
partition, after the cp there didn't work).
The first time it locked up, I did a umount/mount, and it seemed to
come back. Then I tried copying to a NFS ext2 partition and it seemed
to go fine (I let it do an extra 100MB before stopping it). Then I
tried copying it to the original partition. It again locked up, but
this time came back without umount/mount, so I'm not sure that served
any purpose the first time.
The console output is below. Nothing interesting got put in the logs.
Any ideas? I could go to xfs or ext3, I suppose, but reiserfs seems
to have the best performance, so I'd like to stick with it if I can.
Thanks for any help.
