IMHO instead of digging into old source code, you'd better try latest
stable version. I was able to start over 300 PV domUs with 16 MBs
memory each for testing purposes, never got the error you mentioned.
It just became so slow at that point so I stopped testing. This was on
RHEL 5.4 with Xen 3.4.1 from Gitco.
