lisp.run is the name of the clisp interpreter, which maxima uses.
So in your calculation, you were evidentily doing a big maxima
calculation.

Yep.

Wow.  It should be very very difficult to crash the sage server, since
it is very much a separate process from anything that does any
computing, and the linking between the two processes is only
via a pseudo-tty, so it's very hard to crash the server -- in fact I know
of no systematic way to do so.

It's likely.
