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).
