Description of problem:

ls -l fails with RPC: buffer allocation failed for task in dmesg and

Version-Release number of selected component (if applicable):

redhat enterprise linux 3 qu3 with 2.4.21-20ELsmp kernel

How reproducible:

2. apply high(er) nfs load
3. system hangs
Actual results:
ls -l hangs in a directory

Expected results:

ls -l completes and returns output

Additional info:

extremely annoying - requires (so far) a reboot of the machine
to clear (nfs client).

Is this reproducable on more than one machine?

What version is the nfs client?

Are you root or a non-root user when you try the 'ls -l'?

This bug has already been discused in length:

I don't understand why RedHat's up2date doesnt give there paying users
a properly fixed kernel. We experience downtime due this bug every few

(The up2date tool gave us kernel 2.4.21-20.ELsmp #1 SMP up till now.)
