На сервере крутиться samba и ldap под sles. C некоторых пор интерфейсs начали "падать", при этом не капитально а через какое-то время снова восттанавливаться.

При этои соответсвенно ping по 1**.*.*.* и 192.168.0.5 не приносят результатов. Проиходит это периодически, в логах:

Не думаю что в этом виновата samba.. Может быть кто-нить знает в чём может быть проблема?
