Description of problem:

We have problems with three Systems running plain RHEL3 update 4.

This Systems have been suffering periodical hangs with different intervals of
stability but with the same symptoms:

- The server stops responding to all services including X-Server (mouse and
keyboard frozen). It still returns ping requests and responds to sysrq.

- We can showMem, showPc, showTasks, shoWcpus

After some trial and error we have discovered that the hangs seem to be
connected with rdist. Our rdist procedure distributes contents from the machine
that hangs to itself and some other machines. This other machines although
having the same configuration (hardware and software) do not experience this hangs.

Version-Release number of selected component (if applicable):

2.4.21-27.EL

How reproducible:

occasionally while executing rdist
