Hallo :)

On mailinglists please reply below the previous post. It's easier to read this way.

Dear Daniel, Thanks for your kind response. As per your above command got below result. but i couldn't see below settings are local.conf,10-master.conf or toaster.conf. Where it's retrieved. default_process_limit=100 default_client_limit=1000 default_vsz_limit=256 M service/imap/process_limit=1024 service/imap/client_limit=1 service/imap/service_count=1 service/imap/vsz_limit=18446744073709551615 B service/imap-login/process_limit=0 service/imap-login/client_limit=0 service/imap-login/service_count=1 service/imap-login/vsz_limit=18446744073709551615 B

My guess is, that service/imap-login/process_limit=0 disables the setting and then default_process_limit=100 applies.

As to where default_process_limit=100 comes from… try: grep -r default_process_limit /etc/dovecot

Greeting Daniel

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)'
