Yield_connection: tdb_delete failed

[Marceau Dominique]

Samba 2.2.1
IRIX 6.5.12
log level 1

Folowing an upgrade from samba 2.0.7 to 2.2.1, I got now this error:

smbd/connection.c:yield_connection(62)
yield_connection: tdb_delete failed with error Record does not exist.

and I can't connect from my clients. My smb.conf file is the same as the
older version and it used to work fine.
What is different between those two versions and how can I make it run again
in 2.2.1 ?

Thank you
