We do way too much stuff in the parent smbd in remove_child_pid(). In particular accessing ctdbd is not a good idea when ctdbd is stuck in something. We've had a case where smbd exited itself with "ctdb timeout" being set to 60 seconds. ctdb was just stuck doing recoveries, and the parent smbd was sitting in serverid_exists trying to retrieve a record for a child that had exited. Not good. This daemon sits there as parent->cleanupd and receives MSG_SMB_NOTIFY_CLEANUP messages that hold the serverid and exit status of a former child. The next commits will step by step empty remove_child_pid in the parent and move the tasks to the helper. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Ralph Boehme <slow@samba.org>
