Has anybody had any issues with auditd causing a panic upon restart

shutdown? We are using Redhat 5.4 with base auditd. We have diskless
clients, thus the /etc and /var are being served from an NFS server. The
following rules cause the system to panic when we try to /etc/init.d/auditd
restart or just shut the system down. We have hundreds of other Redhat
clients with local disks and have not had any problems with these rules
until we tried diskless and NFS.
We can comment out the rules listed below and then no problem, but we want
to watch /etc and /var. I assume it’s something to do with NFS but can’t
track it down. Any ideas? Thanks.
There was an issue with watch rules. Eric had a patch back in April
that I thought was supposed to land upstream for 3.5 but I don't see
it on
git.kernel.org.
I'm not sure if this would be affecting you since I think the -F dir=
are tree rules rather than watch rules. Do you have any actual watch
rules installed?
Example of rules entries that are expected to be causing issues:
-a always,exit -F arch=b32 -S chmod -S fchmod -S fchmodat -F auid>=100 -F
auid!=4294967295 -F dir=/etc -k sro
-a always,exit -F arch=b32 -S chmod -S fchmod -S fchmodat -F auid>=100 -F
auid!=4294967295 -F dir=/var -k sro
-a always,exit -F arch=b32 -S chown -S fchown -S fchownat -S lchown -F
auid>=100 -F auid!=4294967295 -F dir=/etc -k sro
-a always,exit -F arch=b32 -S chown -S fchown -S fchownat -S lchown -F
