[samba] Частые падения самбы при работе с smb4k

[Kharitonov A. Dmitry]

При работе с сервером через smb4k, сервер часто входит в ступор, 
отказываясь принимать соединения. smb4k при этом сообщает:
Could not connect to server SERVER
Connection failed: NT_STATUS_CONNECTION_REFUSED
Перезапуск сервера восстанавливает работу.
Как избежать частых падений и возможно ли восстанавливать сервер 
автоматически.
