    How can I allow (raise) more than 100 dovecot processes?

    I have about 2-3 dovecot restarts per hour ...

    I have already tried some settings but it does not change anything:

    thanks I have changed and added the part & restarted dovecot but it still shows 100 for:

    Code
    1. default_process_limit


    Code
    1. doveconf -d | grep default_process_limit
    2. default_process_limit = 100

    you must put more than 100-- 100 is what dovecot brings to your system ..


    You should put a minimum of 200 and see if your system by memory requirements is supported


    /etc/init.d/dovecot status


    Excuse me, my english, I use a translator

    hmm, now I have set to 500 ... but default_process_limit still shows 100


    dovecot status shows:

    Main PID: 27789 (dovecot)
    Tasks: 200 (limit: 4915)

    can I use following command to get the default_process_limit?

    Code
    1. doveconf -d | grep default_process_limit

    just include in /etc/dovecot/dovecot.conf the line with the number of processes ... with this change it should work .. even if your config says it has only 100


    And when dovecot reniciar do not get any warning that you want to get too many connections for your configuration in other module



    auth_mechanisms = plain login cram-md5 digest-md5

    disable_plaintext_auth = no

    default_process_limit = 300


    and restar dovecot


    ----

    If I include more processes than there are in other modules by default configured when restarting dovecot .. it warns that it is not possible to manage them


    default_process_limit = 1000


    /etc/init.d/dovecot restart


    doveconf: Warning: service auth { client_limit=1000 } is lower than required under max. load (3000)

    you must already configure /etc/dovecot/conf.d other files to readjust the number of processes and connections to your imap
