While true, I had the exact same behavior when running the jobs in dom0
and it had 800Mb of memory allocated. I think the problem is in the CIFS
bits of the kernel, but that's just speculation on my part.
When I use rsnapshot against linux hosts, no crash. One Windows box at a
time, no crash. Two linux boxes at a time, no crash. Two Windows boxes,
crash in 30 seconds or less -- every time.
At least I have a workaround until it's fixed. I've filed a bugzilla with
redhat on this issue.
