strange system behavevior

Wed May 12 05:22:58 PDT 2004

Sorry for not choosing a more specific subject line, I've got no idea what's 
going on with my system. Please help me to find out.

My problems started a few days ago when I updated security/cfs to version 
1.4.1_1. After doing that, clear text access to encrypted directories was no 
longer possible.

#mount -o -U,port=3049,intr,nfsv2 localhost:/null /crypt

$ cmkdir new
$ cattach new NEW
$ ls /crypt/NEW/     --> shell doesn't respond any more; kernel: pid xxx 
(cfsd), uid yyy: exited on signal 10

I rebuilt world, kernel and cfs using very conservative CFLAGS settings - 
without any success. Tried the GENERIC kernel - same result.
So I downgraded to cfs-1.4.1 which works fine. I notified the cfs maintainer 
who couldn't reproduce the problem.

Yesterday I tried again to upgrade, and it seemed to work. 
But another problem appeared which apparently doesn't seem to be cfs related. 
ls(1) crashed when reading a normal directory. I was not able to reproduce 
this.

> ls rescue/fred/txt/
Bus error (core dumped)
> ls rescue/fred/txt/
showthread.htm

This morning the cfs problem reappeared, I had to downgrade again.

I've checked my disks (using the scsi controlers verify disk utility) and 
memory (memtest86) - everything seems to be ok.
Nothing unusual in the logs.

Any hints on how to proceed? 
Thanks a lot in advance.
