This should be just "process_limit" without "default". But it's
unnecessary, as you set globally default_process_limit.

It is the "imap-login" process_limit that is reached. With the set
default_process_limit=300 this shouldn't happen. So maybe there is some
setting somewhere else, that is not shown. Please supply the output of:

doveconf -S | egrep '(default|imap/|imap-login).*(limit|service_count)'
