Hi there Giles,

not really a solution to your problem, but a hint: Try activating "verbose_proctitle = yes" in your dovecot.conf, restart service dovecot and you might get more information (when the load is produced by logged in users) - it gives you verbose information about which specific user with which IP is generating the high load.

All the best, Megodin

Hi Megodin,

Thanks for the advice, I have added that to my configuration, and will review the logs the next time the problem surfaces.

Thanks

Giles
