Goal

Observed a couple of errors in the imap logs and would like to know the meaning of "Excessive number of users" and "Could not add imap user to the list"? What is the impact?

According to counterutil in some dbhang data, the max it has been up to is 37064.

There still exists a small number of connections to port 143 on the MMPs, which translates to port 143 on the backends. So it is possible that imapd processes could be at maxsessions-1 and an SSL connection and non-SSL connection was received at the same time.
