I tried digging it all through. I can't find a solution.

The problem pops up in auth-master-connection.c in function master_input_request. It does a auth_client_connection_lookup with the "client_pid" (which behaves as a counter, where i would expect a constant process-id...) Something is very wrong with this PID.

Maybe someone can explain the Master <--> Auth IPC to me so I can understand and fix it myself? Where does Master take this client number from?

Hints are highly appreciated, Peter
