Hi Stefan,
I've just posted a patch to qemu-devel that fixes two bugs that
we found; I've only tried a small stressapptest run and it seems
to survive with them (where it didn't before); you might like to try
it if you're up for rebuilding qemu.
It's the one entitled ' [PATCH] Fix two XBZRLE corruption issues'
I'll try and get a larger run done myself, but I'd be interested to
hear if it fixes it for you (or anyone else who hit the problem).
Dave
