How to get rid of server message "Core Dumps"



  • Hi,
    I’m always keen to have no error messages in logs.
    like this one:
    Coredumps will not be generated: kopano-server requires the fs.suid_dumpable sysctl to contain the value 2, not 0. See kopano-coredump(5) for details.

    Very simple to be removed (http://webplay.pro/linux/enable-core-dumps-rhel-7.html)

    mkdir /opt/corefiles
    chmod 0777 /opt/corefiles

    Add the line below in /etc/security/limits.conf

    •           soft    core            unlimited
      

    And create file /etc/sysctl.d/100-cores.conf with this content:
    kernel.core_pattern = /opt/corefiles/core.%e.%t.%p
    kernel.core_pipe_limit = 0
    kernel.core_uses_pid = 0
    fs.suid_dumpable = 2

    Reboot - one line of error messages less :-)



  • The error is there for a reason - AFAICT your config file specifically asked for coredumps by way of “enable_coredumps = yes”. If you do not want them, drop the line from the cfg.
