Arun, You are running into a firwire problem. I have
been there done that with firewire, Once I switched to
SCSI the problems went away. 

Some of this is a OCFS issue but it is more of
Firewire issue. I also found the same the same FW
cards may have parts from different OEM's and
different BIOS's. 

I ran this test on 6 different Dell 1650 clusters  all
with same problems. I tried RHAS 2.1, RHEL 3.0 and
SUSE SLES8. SUSE gave me the best results over Redhat
but still had major firwire and OCFS issues. Once I
went to SCSI the problems went away.

Hope this helps,
