Had increased the tombstone lifetime back to 170 days and after all 
deleted object where purged the error was gone. Continued decreasing 
lifetime in 10-20 day steps.
Usualy samba need a few minutes (~5) before the purgin starts after the 
lifetime value was decreased. An restart of samba triggers the purge 
immediate.
