RHEL 5 auditd crashes the machine at roll over
Posted on 2011-09-26
I have a RHEL 5.4 server that has an autofs mount to a nfs share to store the audit logs. On this server when the logs do roll over it drops the nfs mount and then starts buffering the logs locally. The buffer fills and then the server locks up and is not accessible via ssh or local login.
Rebooting the machine requires the following actions to be completed before auditd can start again:
mount logserver:/loglocation /loglocation
service autofs restart
service autofs reload
Then we check to make sure that the loglocation is populated with the folder name of the server
Then we have to change the permissions of the audit.log file to allow for the machine to write to them again:
chmod u+w /loglocation/servername/audit/audit.log
That allows us to start the audit service:
service auditd start
All actions are done as root or sudo, this will allow the logs to work properly until the next roll over. We have not been able to find a solution that keeps the nfs mount active after a roll over.
Thank you for your time,
