[fetchmail-users] fetchmail daemon problem

[Martin S. <mar...@in...>]

Hello,

I'm running fetchmail 6.2.5 version of fetchmail from Debian Etch 
package. I noticed that the daemon fails retrieving IMAP mails after a 
certain time. I launch fetchmail as daemon with the init.d script 
provided by debian. To analyse the problem, I added -v option, and here 
is the full log illustrating the problem. It is quite long but quite 
clear too.

I'm running Exim 4, procmail, courier imap. 3 polls are configures, 
POP3, IMAP4 + SSL, IMAP4

First here everything's ok, for hours or even a day:
