PPS: I learned another thing today: I have to disable kernel logging in the containers. Sorry about that. The nfsd died again today, but I doubt that the new log files are very useful. Please mail if you are interested. The NFS server has been rebooted (without imklog syslog module in the containers) and the watchdog has been started again. Regards Harri
