IRC Connection Delay Problem

Hello, all.

I'm running ircd (ver. 2.10.3p.7) on my desktop.

Now, I can connect to my irc server and everything seems good,
except one promlem.

When I try to connect to my irc server, delay occurs about 20 secs.
I checked config.h and ircd.conf, but found nothing to help this problem.

Delay occurs after subscribing nick and id, exactly. (see below)

nick :myNick
user MyID 0 * :description about me

(... about 20 secs delay ... )
