[Ocfs2-users] Reg: Server getting kernal panic due to OCFS.

[vasanth.chellam]

Hi All,

 

I have two Linux nodes with RHEL 4.5 32 bit OS and i'm using OCFS2 1.2.9 in
it. Out of two nodes one node got kernel panic. Post rebooting the node its
up and running. As per log analysis i found the following error in 

/var/log/messages. Pls let me know what is the cause of this error and what
can be done in order to fix it.
