    Critical fix for Imunify 4.8.x?

    Is it possible to downgrade to version 4.7.x ?
    Or do we have to remove Imunify completely until the critical bug is fixed? Do you have any eta for the fix?

        Hi Morten,
        Thanks for waiting. Presumably this is happening due to the fact that sometimes the number of running PHP processes spikes enough to make imunify360-php-daemon hit the maximum number of open files threshold.
        That maximum number of open files is specified on a service level and defaults to 1024.
        The imunify360-php-daemon version 1.1.3-1 that has been installed along with the latest update has this limit increased to 4096 by default through the system unit.
        As a workaround, the limit can be increased by executing

        Code:
        systemctl edit imunify360-php-daemon
        and saving the following:

        Code:
        [Service]
        
        LimitNOFILE=4096
        After that, please execute

        Code:
        systemctl restart imunify360-php-daemon
        If the above doe not resolves the problem, please get back to us with a ticket https://cloudlinux.zendesk.com/hc/en-us/requests/new so that we can take a closer look at the problem.
        We are still working on a permanent fix, it will take several days.
        Thank you for understanding.
