-ERR: unable to write pipe

Hello,

I need urgent help from qmail experts.
Here is the summary of my system.

- Gentoo 2.6.16-r7
- qmail 1.03-r16
- ucspi-tcp 0.88-r14
- checkpassword 0.90-r2
- vpopmail 5.4.16
- courier-authlib 0.58
- courierpassd 1.1.0
- squirrelmail 1.4.6-r2

I set up virtula domain, say "example.com" and created a user
"user@example.com".
Squirrel mail works well.
But when I tried to access "user" email via pop3 client, I got the
following error:

-ERR: unable to write pipe

I googled this and didn't get any solution.

Please help me.
Here is a "ps ax" command result:

if you run the command /var/qmail/bin/qmail-popup example.com
/bin/var/vpopmail/bin/vchkpw /var/qmail/bin/qmail-pop3d Maildir what
happens?
are you using user@example.com for the user name or just user?

tail -f /var/log/qmail/qmail-pop3d/current what does it say there when
you make your connection attempt?

Is this the correct path where vchkpw is installed?
/bin/var/vpopmail/bin/vchkpw
