Hi,
I am running ocfs2 cluster on 6 nodes. The OS version is RHEL 5.7
(Kernel :- 2.6.18-308.1.1.el5) and the ocfs2 rpm versions are as below,
[root@prod37 ~]# uname -r
2.6.18-308.1.1.el5
[root@prod37 ~]# rpm -qa |grep ocfs
ocfs2-tools-devel-1.4.4-1.el5
ocfs2-2.6.18-308.1.1.el5debug-1.4.7-1.el5
ocfs2-2.6.18-308.1.1.el5-1.4.7-1.el5
ocfs2console-1.4.4-1.el5
ocfs2-tools-1.4.4-1.el5
ocfs2-2.6.18-308.1.1.el5xen-1.4.7-1.el5
ocfs2-2.6.18-308.1.1.el5-debuginfo-1.4.7-1.el5
ocfs2-tools-debuginfo-1.4.4-1.el5
Frequently one of the nodes in the cluster is goes to panic state and
requires hard reboot to bring back the system , the alert log contents
on the panicked node during this period is as below,

Is this a known issue ? Any fix ?
Regards,
Ravi
