    Hi!

    Anybody had this problem?
    On random periods pop has very big delay on connection. On normal working pop
    telnet localhost 110
    immediately gives: +OK Hello there.
    but when the lag comes, after telnet it's about 1-5mins after
    +OK Hello there.
    comes. Anyone had this problem?

    Go on, have a guess
    I would guess that you've either hit the maximum number of concurrent connections, or perhaps there's a problem with the servers DNS resolvers.

    When it get's to this lag- every new pop connection is opened and I see how number pop connections is getting high. DNS is ok - resolve.conf is like any other server, I can ping some addresses that I've never pinged before with no problem. What is curious - when I do:
    1. telnet localhost 110
    2. -- it's connected but no any response
    3. If I will do 'service exim stop'
    "+OK Hello there" is showing up as soon as exim is getting stopped.
