Re: cyradm login loops

    Occasionally, I see something mentioned about tracing a particular
    cyrus process to determine what's going on (or wrong, as the case
    may be).  How is this done?  I'm not getting very far at resolving
    my particular problem, so I'd like to know what the proxyd process
    thinks it's doing each time it spawns a new connection to itself.

      have recently upgraded to cyrus 2.4.6.  Our environment includes a

      two front end servers.  If we mistakenly create a user mailbox on
      one of the front end servers using cyradm, and then try to manage
      it (dm, sam, info, lm), cpu load on the front end server increases
      until the box is unusable.  Syslogs show the user cyrus (our admin
      user) logging in over and over, each time creating a new proxyd
      process, which explains the high cpu load.
      

      Managing mailboxes on the back end servers from the front end
      servers works fine.
      

      Here's my imapd.conf for one of my front end servers:
      

      configdirectory: /var/lib/imap
        

        partition-default: /home/imap
