POP server goes up and down

Hello all, just wondering if anyone can point me in the right direction...

I had a few users tell me they get pop3 errors.. like in the email mentioned below..

Compte : 'mail.dido.ca', Serveur : 'mail.dido.ca', Protocole : POP3, Port : 110, Sécurisé (SSL) : Non, Numéro d'erreur : 0x800CCC0F.

Sorry for the French... but the error numbers speak for them selves...

My conf looks lke this for POP

listen pop_proxy XXX.XXX.XXX.XXX:110

      maxconn 500
       mode tcp
        log global
       balance roundrobin
       server peter XXX.XXX.XXX.YYY:110 check inter 5000 fall 4 rise 1
       server joe XXX.XX.XXX.ZZZ:110  check inter 5000 fall 4 rise 1
       stats enable

I was wondering if it could be my conf file and options that might cause this or it is something actually on the back end server? Of course i understand the backend server stuff is my problem and should not be discussed on this list... :)

Here is a log output... maybe i should up the logging to info?

Thanks for any help..

I love HAproxy!
