    Hello everybody,

    I moved a Domain from our old System to ISPConfig . This System runs perfectly for 10 months, but now:
    Code:
    host:~# free -m
                 total       used       free     shared    buffers     cached
    Mem:           444        440          3          0          0         13
    -/+ buffers/cache:        427         16
    Swap:         2047       1763        284
    
    I know it's not much ram, but normally there are just about 200 MB used and I increase it as soon as I can turn off the old system's VM.
    ps aux:

    As you can see, just web19 - the new one - is affected. This problem appears sometimes.. what could be the problem? It seems like a loop, could it be the forwarding rules?
    There are some rules like:
    [email protected] forward to
    [email protected]
    [email protected]
    [email protected]
    etc.

    Maybe that creates a loop?

    I'm glad about any hint.

    Thanks

    Sven

    This behaviour is normal. Forwarded emails get scanned separately when they arrive in every single email account. If you want to speed this up, switch to clamd.

    till This behaviour is normal. Forwarded emails get scanned separately when they arrive in every single email account. If you want to speed this up, switch to clamd.

    Hello Till,

    thanks for your hint. But for me it seems to be more, because there is not so much traffic on that host.

    Example: A Mail to [email protected] is scanned one time on receiving. Let's say [email protected] is forwarded to [email protected], [email protected],....,[email protected] - than there will be 11 spamassasin and clamav checks of the same mail - am I right?

    But lets say there are 50 Mails checked, why is my system going crazy like that? A spam and virus scan isn't that complex I think.. and there are never more mails then 50 in the queue! There are always the same ~37 mails in the queue.

    I will change to clamd, but I'm afraid that this will not solve the real problem..
