Is it causing a kernel panic?  I didn't get that from his posting.  I
saw that the kernel was reporting that a process had crashed, the zip
process with pid 2351.  If it was a hard lock, I assume he would have
stated so...

But the process is repeatable for the zip application right?  So, it
doesn't sound intermittent.  It's behaving exactly the way the binary
wanted :-)  Ie, it is either a bug in the source, which appeared in
the binary, or the binary is corrupted, or a shared library is the
issue.  That's why I asked if i twas happening in many different
applications, to which he hasn't responded.

In any event, if you have 30 other machines, what is so different
about this one machine, and when was the last time it was working
after a reboot (indicating new kernel/libc loaded, etc)?
