Too many open files

[Peter Peters]

I installed MailScanner 3.22-7 on friday. Saturday the mailserver
started running out of open files. The logging seems to indicate
problems in Sendmail but nothing changed regarding sendmail.

The problem seems to be related to large numbers of UDP sessions to
nameservers. Anybody experiencing this kind of problems?

Information:
20.000 - 30.000 messages a day
4.000 - 5.000 spams a day
10 BL's active in MailScanner (0 in SpamAssassin)
8.000 Open files maximum
