The message repeats until there are free connection slots again.
Yes but since the other processes never finish, there are never free
slots again until I do: svc -d qpsmtpd; svc -u qpsmtpd
I think you should use strace or something like it to find out what the
processes are waiting. Don't exclude the possibility of a malicious
client that just keeps connections open.
I will indeed try to strace -p on the various processes and see what
they are waiting on. And about the possibility of a malicious attack, I
find this unlikely as the hosts connecting are different, and most are
legitimate.
Thanks! :)
