This assertion comes up while running an XP Guest having 2GB RAM on a 8GB Host. Host OS is Debian Lenny on AMD64.

The session is eating a lot of its RAM during the operation. No cut'n'paste was involved during the crash.

I've upgraded to 2.2.2 the day before yesterday.
Did not have this Meditation since, although I had some heavy jobs running on this guest.

Seems to be fixed by 2.2.2 to me.

Thanks for the feedback.
