The state of the processes according to ps is "S" which means "interruptible sleep" as far as I know?
What is also interesting is, that the processes, that seem to have this problem are not shown with the owner name but with the user ID. Normal imap process in ps aux: username 10841 0.1 0.1 9148 3472 ? S 13:18 0:04 dovecot/imap Imap Processes that seem to be quite old already: 1405 11099 0.0 0.1 8072 2644 ? S 13:23 0:00 dovecot/imap But I am not sure if this is really linked to the problem. Benedikt.
