    since this morning I can no longer add new hostings to IMSCP (latest)

    Code
    1. [Tue May 7 09:12:25 2019] [fatal] iMSCP::DbTasksProcessor::_processModuleDbTasks: Modules::SSLcertificate::_loadData: DBD::mysql::db do failed: You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version
    2. ...propagated at /var/www/imscp/engine/PerlLib/iMSCP/DbTasksProcessor.pm line 496, <$fh> line 184.

    libdbd-mysql-perl is already installed

    Something seems to have gone wrong w/ sury.org ... it worked until this morning and now I get many checksum errors for sury.org packages:

    is this archive already deactivated or can I add a new key and continue w/ the sury updates ...

    or should these sources be removed completely right now?


    Code
    1. W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://packages.sury.org/php stretch InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B188E2B695BD4743
    2. W: Failed to fetch https://packages.sury.org/php/dists/stretch/InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY B188E2B695BD4743
    3. W: Some index files failed to download. They have been ignored, or old ones used instead.

    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

    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:

    it's an ip-set blacklist which make use of some major BL too f.ex. Spamhaus ... attacking IP addresses are set to reject and in this case the letsencrypt verification server was blocked. It's not a plugin issue but maybe this information helps when using external blacklists or fail2ban RBL rejects too.

    yep, the letsencrypt IP address is blacklisted (Spamhaus SBL-XBL Combined Block List) ... if anyone uses ip-set blacklists you should whitelist 64.78.149.164
