Hi!

I just noticed a crash..

When a userlevel application (running as "nobody") tries to resize an
incomplete image file using libimagick, the virtual machine crashes...

For some reason the ids 3 4 and 5 refers to the same machine. I crashed
it a few times, but when crashing it didn't go out of the "xm list"
list. but if I just re-run "xm create /etc/xm_dom2" it's restarted.

Note: the same process does *not* crash on non-xen machines.

I searched a bit on google but couldn't find anything interesting.

Anyone have an idea of why it happens, and if a fix is planned/available
somewhere?


Mark
