Today I switched one of our servers from Courier (deployed 3-4y ago) to DCrc7. Everything seemed very nice (system load dropped significantly).
Unfortunately after some time and ~8000 pop3-logins the main DC loop just quit without _any_ notice. Some pop3-login childs still showed up in the processlist, but the main listener on port 110 was gone.
The above described scenario has been observed 2 times.
Any suggestions are welcome.
System: Debian 3.0 woody, Linux kernel 2.4.x
