yes, this was the reason. Many thanks for your tip.
I had a hugde swap space and therefor a big tmpfs in /tmp and /var/tmp
but my /dev/shm was just 512MB and this is a joke for 8-12 UML
instances. Maybe the 2.6.17.x kernel uses more /dev/shm(?); this problem
never occours before.

Now my shm is about 2G and the host and all UMLs are well alive :)

Thanks and greetings,
stefan
