Can you send me your OOM killer output from /var/log/messages - I want to see if it's the same one that I am hitting. If we increase our memory to 384MB of higher, we don't get the OOM killer - at least we have not seen it yet (we want to keep dom0 to 256MB). Eric

just wanted to say, that i'm facing probably the same problem with XEN
3.1 and 256MB RAM in dom0. I also had this with 512MB but not so often.
Sometimes this happens if i "dd" a new file-image (10GB) in dom0.
