That's it, thank you!
Using standard Ubuntu "server" Kernel brings in the case of heartbeat
some problems. Using standard Ubuntu "686" Kernel anything related to
heartbeat works fine, also after restarting the machines.
So is this a Kernel problem? Or better, a Ubuntu-Kernel problem?
Should I file a Bugreport to Ubuntu?
The Kernels are not very different, but the Scheduler.
