xinetd fails on some services with Address already in use

[Jacques Beigbeder]

Hello,

Distribution: FC4 x86_64, up to date.
Host: used an a NIS client (passwd: compat, and so on
in /etc/nsswitch.conf)

My problem: on boot, xinetd fails to start some services with:
(syslog output)
	bind failed (Address already in use (errno = 98)). service = imaps
	Service imaps failed to start and is deactivated.
	bind failed (Address already in use (errno = 98)). service = pop3s
	Service pop3s failed to start and is deactivated.

After analyzing, it happens that sometimes NIS requests use TCP/995 for
a *short* period of time. So:
- it is very hard to have lsof(8) displaying TCP/995 in use;
- but tcpdump displays traffic between my host and the NIS server
  on TCP/995;

The result is that xinetd fails to start with all services!!!

My question: how to fix that?
(I really need imaps and pop3s and NIS...)
