Kernel BUG at inode.c:384!

[Umaid Singh Rajpurohit]

Hello all,

we are running clearcase,sun grid engine on RedHat Linux 7.1 
(kernel 2.4.2-2smp) on IBM Xseries one U servers that has
two CPU's and we mount all the files to be processed using 
autofs.
Here is uname -a
Linux  2.4.2-2smp #1 SMP Sun Apr 8 20:21:34 EDT 2001 i686 
unknown

I have more then sufficient physical memory and swap space
Here is some swap space detail form top

Mem:  1543868K av,  507684K used, 1036184K free, 0K shrd, 317576K 
buff Swap: 5116576K av,0K used, 5116576K free 33076K  cached

we are running n number of IBM X Series server every one or 
another day I get this error.

   The /var/log/messages says something like:
