Description of problem:
We are running a cluster of 16 Dual Xeons (Supermicro X5DPR-iG2).
The m'board is based on the 7501 chipset with onboard dual Intel PRO1000
NIC's. There is heavy cpu usage 24/7 and the network traffic can be heavy but
intermittent. Over the last 6 months we have experienced random lock ups on
several different nodes. We have not been able to reproduce the problem at
will but it recurs every few weeks. After the lockup the computer still
responds to a ping but not to a remote or console command. A reboot always
clears the problem (until the next time). There are never any messages in the
system log files. We observed this problem with the stock RH8 kernel and then
upgraded to 2.4.20, which exhibits the same problem.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run 16 nodes with heavy cpu and heavy but intermittent network traffic.
2. Wait 1 month
Actual Results: Periodic freezing of one of the nodes
Expected Results: Kept running
There are similar bugs listed, but I am not sure they are the same. They seem
to occur more frequently for one thing.

Can you try the latest errata kernel ?
It's possible you're being hit by some of the obscure bugs fixed in 2.4.20-20
I updated to 2.4.20-20smp last October as you suggested, and more
recently to 2.4.20-28.8smp. There has been no recurrence so I
consider the issue closed.
Thanks for the bug report. However, Red Hat no longer maintains this version of
the product. Please upgrade to the latest version and open a new bug if the problem
