Still having these problems.
Have replaced server with a much stouter machine but the number of
processes for dovecot remains the same.
Is there a way to increase the dovecot processes?
I tried this to no avail:
https://support.plesk.com/hc/en-us/articles/213953065-Roundcube-login-fails-with-Connection-to-storage-server-failed-process-limit-100-reached
While it looks like the correct idea my guess is implementation in BO
might be different. Since it didn't seem to work I removed the file and
restarted mail processes in the GUI.
This 5209R machine's primary purpose is to provide email for about 140
users. Load averages never exceed 25%, memory 75%, disk 20%.
Current emails surrounding the problem look like this:
