[Mailman-Users] problem with mailman and qmail-ldap

[gabo]

- mailman 2.1.5-9
- apt-get
- Linux Debian testing.
- MTA : qmail with ldap.

My problem is :

I have run mailman with an qmail-ldap server.Once or twice per day, 
mailman not delivery mail.
The mails are received in qmail-ldap server and it calls  
/var/lib/mailman/mail/mailman post listname.
I checked it, qmail receive the mail, however the mailman not send. Then 
i restart mailman and all mails received are sending.
The problems had began when i updated the libc6 four days ago. The 
version the libc6 is 2.3.5-6.
What is my problem ?

Thanks you

Gabriel
