Hi,

I re-installed 5.4 on the server and below was the pid trace when it 
panic'ed. I rebooted and panic'ed it again to be sure. Both time, it got
the same pid. It just panic'ed by itself when the network traffic started 
to build up. I had top running, but I could not really finger any one 
program that caused it.

Thanks for looking into this!

Regards

5.4 panic at lockmgr - update

Did I read somewhere that you need PAE enabled for over 4GB of ram?  I could be
horribly wrong, but my 0.02p worth :)

Hi,

I re-installed 5.4 on the server and below was the pid trace when it
panic'ed. I rebooted and panic'ed it again to be sure. Both time, it got
the same pid. It just panic'ed by itself when the network traffic started to
build up. I had top running, but I could not really finger any one program that
caused it.

Thanks for looking into this!

Hi,

Yes, PAE was enabled. Below was the dmesg output I posted with the original 
post. Thanks for taking an interest in this.
