Red Hat Bugzilla – Bug 164151
NFS server freeze with kernel-2.6.9-11.EL
Last modified: 2012-06-20 09:28:06 EDT
Description of problem:
Booting from or installing via NFS does not work with the latest RHEL-4 kernel
on the server. Clients report in install: "server not responding, still trying".
Transfering lots of data to the NFS server freezes NFS after a moment and
results in high load on the server. Only a restart of NFS resolved the problem
for a moment.
Booting kernel-2.6.9-5.0.5.EL instead resolves the problem completely.
The bug is similar to #152102, but the server is RHEL-4 (i686) and the clients
are FC-3 (i686 and x86_64) or FC-4 (i686 and x86_64).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Setup NFS server with kernel-2.6.9-11.EL.
2. Transfer data to or from the server.
3. Transfer aborted.
NFS service freezes.
Is there any type of error message on the server as
to why it stop sending? Posting an system trace
(i.e. echo t > /proc/sysrq-trigger) of the server might
