  • /usr/bin/imapd maildir

    Hi all,

    Looking at htop on one of our interworx servers we can see that /usr/bin/imapd maildir is sit at 90% to 100% CPU.

    Is this normal usage?

    Cheers,

    Hi Bertie

    No, it should not be anywhere near those levels I believe, unless you have a lot of clients accessing very large mailboxes

    I would restart qmail and see if this normalises the imap usage

    Is it just to 1 client

    Many thanks

    John

      Hi,

      This server does have a lot of email accounts on there.

      I've killed it and the process is no longer using that much of CPU and email services are still running okay. We shall see how it goes!

      Thanks again,

        I had this problem, not because the amount of accounts, but because of maybe 10 email accounts that have multi-gigabyte inboxes. Even if they just move the email out of the main INBOX folder, it helps, but basically every time they view the inbox to check for incoming mail it puts a hell of a load scanning through all the emails. Thousands of small files.

        Because of this I finally upgraded to a server with an SSD drive. That and a faster CPU have cut that load to almost nothing now!
