The funny thing is - I have four machines running my p2p code. Of
course,
I'm disorganized so they all run various base images :), but the p2p
code
is the same. One image (on Linux) locks up very quickly; another image
(on
Win2k) locks up now and then, the two other images (one on Win2k, one on
WinXP) just keep on running.
==========================

It could be that it has nothing to do with my previous experience.


==========================
I lowered the priority of all p2p-related processes to 20. No special UI
code is running so even if I horribly deadlock my own threads, I would
expect that I'd still be able to get a response from Morphic.

That's why I'm a bit at a loss why this happens...
==========================

I think I caught elsewhere that you said even the VM is clobbered.  If
that's the case, my callstack idea won't buy you much, if anything.

Absolutely!
==========================

I will dig around for it.  There are a couple of aging machines that
should have it.  Hopefully they still run, and if not, I might be able
to get the drives to work in another box.  I doubt it will help you in
this siuutation, but I think it will be a useful addition to Squeak
(otherwise, I wouldn't nag about it every year or so<g>).
