And a 3rd crash.  I had set debug.ddb.textdump.pending to 0 hoping that
it would cause the scripts to run.  It didn't, and we didn't get
a textdump at all (system rebooted on it's own).

Is there a limit I can set that would leave enough memory for the
(de)compression stuff should have enough memory?

Currently running with no tunables set.
