Hi!
Ich bringe das Thema mal wieder nach oben. Ich habe auch bei Pretago einen Server und exakt das selbe Problem. Aber bei mir sind auf dem Pretago vServer nichtmal Spam Assassin oder ein Virenscanner installiert, trotzdem überschreite ich regelmäßig das numfile-hardlimit von 2500 (bzw. stoße ich dran, der Server bleibt quasi stehen, vor allem der Mailverkehr geht dann nicht mehr).
Hier mal die top-Statistik, die sieht ganz normal aus:

Ich habe nix drauf - lasse die Standardkonfi vom Server laufen, paar HTML-Seiten, paar Mail-Adressen (6 POPs, die vll. 200 Mails pro Tag bekommen). Kein MySQL, kein PHP (hatte ich drauf aber bereits testweise gelöscht, trotzdem ist es nicht besser geworden).
Irgendwelche Ideen, was ich machen kann / wie ich den Server dauerhaft aus der Yellow oder Black Zone bekomme?
Danke!
Alex
