Hello,
The default_process_limit parameter is limited to 200 On my server there is a lot of connection imap and this figure is quickly reached And users can no longer connect
If I try to increase it I get this error message
Warning: service auth { client_limit=1000 } is lower than required under max. load (1100) [....] Restarting IMAP/POP3 mail server: dovecotdoveconf: Warning: service auth { client_limit=1000 } is lower than required under max. load (1100) Warning: service auth { client_limit=1000 } is lower than required under max. load (1100)
How do I solve this problem?
