Please include a link to hs_err_pid1832.log.  Also, anything you can do to
cut down what is needed to reproduce would be helpful.  I don't think many
people likely have such a set up.  In that case there may well be some back
and forth to gather more information from the crashes unless the crash file
is clearer.

Yes please.

It seems unlikely, but that would rule it out for sure.
