Alan,
<p>On a client running all by itself on our production network overnight,
doing an "ls -lR&nbsp;/usr" and doing a compile (in a loop) is giving the
same problems.
<p>A little snipit from /var/log/messages

<p>Shows that under no (or little)&nbsp;load this thing is failing.
<p>We have 20 networks with ~100 machines on each with this same problem.&nbsp;
Only a few at a time are using Linux.&nbsp; We are trying to promote Linux
as a great operating system, but this is not helping.&nbsp; Again the samba
on win95 is puring along nicely plus every other service but for NFS.
<p>We have changed the NIC on this server to 3Com 3c90x for no change in
status.&nbsp; Clients are using&nbsp; CNETPro120 200 and Intel eepro100
<p>The servers are generally PIII500&nbsp; 512MB RAM.
<p>We have tried mount flags rsize=1024, 8192, 128, with no change.
<p>It looks like a server issue related to RPC.&nbsp;&nbsp; But I am only
guessing here.
<p>Any more help is much appreciated.
<p>Thanks

<p>The request queue slot message means the server isnt responding (at
least in
<br>the eyes of the client). Given you can get into the box that isnt the
<br>net card (at least not now). What mount options do you use ?
