[Xen-users] domains > 40 fail to start correctly.

I have a dual quad core server with 48G of dram. I notice thateverything works fine up to domain #40, but subsequent domainsdon't start correctly - they consume inordinate amounts of cpu and youcan't connect to their console.

It's not the particular domain that's bad - I can kill a domain to getbelow the 40 threshold and then restart 'netbsd.002' (for example)

and it will run ok.

Any ideas?  This is using netbsd as dom0.
