ProFTPd – Z dnia na dzień przestało działać


Nie wiem, jak mogło się to stać. W konfiguracji nie było nic zmieniane, w bazie danych również wpisy są takie same, a FTP przestało działać dziś, a cały czas działało. Podczas restartowania nie wywala żadnych błędów, w logach również. Mam tylko takie coś:

Co się mogło stać?!… <myśli>

Bazę dany mam na innym serwerze dedykowanym (również w OVH).
Zrestartowałem tamten serwer i o dziwo proftpd działa, tylko pytanie dlaczego tak się stało? Logowałem się bez problemu przez PMA do tej bazy, przed restartem, to powinno działać.
