Problems with NFS/rfs

[STEPHEN SCHERR]

Dear Netters:
  We have a bunch of 4D's ethernetted together, and about 2 weeks ago our
main file server started generating thousands of
	rfs_read: attempt to read from non-file
errors (both grcond and unix log them to SYSLOG).  In fact, enough messages
are generated to disable logins (I guess because the system is busy handling
them).  I can stop the messages by un-exporting the file systems;  they
start up again when I export.  Sometimes, however, the machine decides to
let me export things for a while if I have waited several hours.

  Has anyone seen anything like this before?  I have reloaded/upgraded OS,
done a mkfs on the file systems and nothing seems to help.
System Info:  4D/220GTX, IRIX 3.3.2 (was 3.2), disks are 1.2 GB SMD.
