Ok, that's it - it is the wdwait() which returns with an timeout error. I've
changed that TIMEOUT to (TIMEOUT*10) and the panic has not occured anymore.
Shall i send-pr it ? (I have the feeling its a PAO speciality, before i had
PAO up and running i had a pure 2.1.6 running for quite a while and it never
occured).
