dovecot: master: Warning: Sent SIGKILL to 100 imap-login processes

Hi,

I am using Dovecot 2.2.32 (dfbe293d4)

I noticed lots of messages like:

dovecot: master: Warning: Sent SIGKILL to 100 imap-login processes

in /var/log/maillog

I commented out "process_limit"

service imap { # Most of the memory goes to mmap()ing files. You may need to increase this # limit if you have huge mailboxes. #vsz_limit = $default_vsz_limit

# Max. number of IMAP processes (connections) process_limit = 1024 }

but it seems that value doesn't change (still 100).

Any suggestions?

Thank you very much!
