Description of problem:
I have nfs mounted an ext3 filesystem from one Red Hat AS3.0 server
to another Red Hat AS3.0 server. The client hangs after cd-ing to the
mount point. Following is the error message in the messages file:
kernel: RPC: buffer allocation failed for task ca77bca8
Any help is appreciated.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.NFS mount the filesystem.
2.cd to NFS mounted file system (e.g. cd /temp)
3. ls -l
Actual Results: The command hangs.
Expected Results: Should have displayed the long listing.
If you are looking for immediate help with this, and have an
up-to-date entitlement, you would be best off calling Red Hat's
Support, 800-REDHAT1, or going to http://www.redhat.com/support
Does this still happen with more recent RHEL3 kernels?
I think this is a dup of bz118839, which should be fixed in RHEL3 U4.
