RE: [Axiom-developer] Axiom crashing in Zope-Plone

[Bill Page]

Hans,

I am VERY HAPPY that you are motivated to do this! I would
like to provide you with as much help as I can.

I tried your demo.py program on the axiom-developer.org system
and it works fine. The program and outout is attached below.
As you can see, I only made a simple change to accommodate the
default location of AXIOMsys and the input file.

Although Bob McElrath has written separately about the issue of
programs that produce a large output, I don't think that this is
the problem since the MathAction axiom code already uses the
"fixed runCommand" (makeNonBlocking etc.) that Bob mentions.

Therefore I think the best approach would be to find the
meaning of the EXITSTATUS 139. I will let you know if I find
anything.

Regards,
Bill Page.
