Unable to start 16th domU

Hi!

While trying to create 20 domUs I got this errors with the 16th VM:

ROOT xen1:~> sh run-xen.sh 16 -c
Using config file "/xen/conf/netbsd.16".
Error: Error creating domain: [Errno 22] Invalid argument


From the logs:


[2005-04-18 13:24:19 xend] ERROR (SrvBase:162) op=create: Error creating 
domain: [Errno 22] Invalid argument
Traceback (most recent call last):

According to the "vnconfig -l" the vnd16 is active and I can manually
mount vnd16a to /mnt.

If I now halt one of the previously started domUs I can start this
domain just fine so it seems there's somekind of limit (15) for
concurrent domUs. Any ideas where that might be defined?
