The problem is: one client command causes a buffer overrun, which
leads to a server crash. This problem is generaly fixed with the
ptf-3 clients, but Linux is a ptf-1.
The verb, that crashes the server, contains the OS version and
revision. So a kernel 2.0.34 is OK, while 2.1.131 is one byte to long.
To solve this problem use a non-hacker linux version, or patch the
version number, this it is shorter than 7 chars (uname -r).

With an other side of view: if you really want to crash the server,
use the hacker linux kernel.

So I think, the IBM server people should make the server more bullet
proofed.
