I  have a cron-job checking for the existence of this error and then  I   reboot dovecot when  I  see this error, but what is causing this error ?  What  I  am reading on the Internet about this particular issue has not helped to resolve the issue.   I  would really like to know how many mail processes it thinks that it is using at any one instant in time.  Is this possible ?  Maybe then  I  can track the reason for the error.

It thinks there are max_mail_processes number of processes running at that time. Which you can find out with:

dovecot -a | grep max_mail_processes
