Hi,
There's an easy fix. In inetd there is some sanity checks which
assume that a program started from inetd can only be done X times per
minute. If you have a busy inetd service, such as pop, you can exceed
this limit and inetd thinks the program is out of control.
So, in /etc/inetd.conf, change:
pop-3 stream tcp nowait root /usr/sbin/tcpd ipop3d
To this:
pop-3 stream tcp nowait.200 root /usr/sbin/tcpd ipop3d
