[Qmail-it] AIUTO!!! Qmail impazzito

[Enrico Morelli]

Salve a tutti,

ho un problema su un server con netqmail+spamassassin+qmail-scanner, che
è andato bene fino a qualche giorno fa. All'improvviso hanno iniziato a
rimanere vacanti dei processi qmail-smtpd e rblsmtpd che finiscono per
rallentare l'invio della posta. Non uso domini virtuali. La coda in
uscita è pressoché vuota. Dai log non appare niente di anomalo e non so
da che parte rifarmi. Qualche idea? Mail bombing?

Segue un ps -ef del server.
