Hello Timo, There is no other problem as far as I know. That's why I think is has something to do with dovecot. Specifically with the imap an imap-login process, as I observe in the processes status. Anyway, the system load is not high enough to cause these problems. However, imap service doesn't work properly.
So, in order to enable the login process in high performance mode I add the parameter service_count = 0. Right? I'll let you know if this helps. Kind regards.

Yes. Is the system load very high? That could explain this. Or do you see any other error messages? Those errors you pasted above show that something is wrong, but not the root cause of what's wrong. > Anyway, I'm going to investigate what David Warden told me about the "High > Security" mode, just in case it is related to my problem. It could at least help reduce the load. Also it would be a good idea to upgrade to latest v2.0. ______________________ This message including any attachments may contain confidential information, according to our Information Security Management System, and intended solely for a specific individual to whom they are addressed.
