First, let me say that I am NOT the expert on this.  But...

The system has indeed trapped an illegal instruction. Whoever installed the
machine selected to have the low-level debugger come up when such things
occur.

Are you running the released level of the software?  If not, get it.

If it is the released level, call the problem in to IBM.  It will probably
be useful to record what shows up on the debugger screen.  There probably is
a way to crete a dump that may be useful to IBM to track down the beast.
