Thanks-

Seems to a kernel Bug. Can you tell me the kernel version which you are using.?.

2.6.9-78.ELsmp
Red Hat Enterprise Linux AS release 4 (Nahant Update 7)


But it was running fine previously.

Hi,

Best solution is to upgrade your kernel version to 78.1 or 78.2 The simple google search of your kernel version sent me to this link "https://bugzilla.redhat.com/show_bug.cgi?id=456997" please follow this link
