    -rw------- 1 root root 5857280 Sep 17 08:21 core.12179
    -rw------- 1 root root 4554752 Sep 17 14:50 core.15409
    -rw------- 1 root root 5349376 Sep 17 14:26 core.1846
    -rw------- 1 root root 4354048 Aug 24 16:53 core.19107
    -rw------- 1 root root 3387392 Aug 24 17:41 core.5627
    -rw------- 1 root root 5050368 Aug 24 17:41 core.5632
    -rw------- 1 root root 4325376 Aug 24 11:10 core.5817
    -rw------- 1 root root 4263936 Aug 24 11:11 core.5844

    They're core dump files from a failed (or crashed) program or process. You can delete them but you might want to look into what's causing them. Take a look inside a few and see if you can find a cause before you delete them.

    You can attempt to find out _what_ is crashing to begin with.

    run the following from an SSH shell: strings <core_filename>
    example: strings core.10916

    You may want to do: strings <core_filename> |less

    Look near the top and you _should_ get an idea of what the actual file was that was executed and crashed.

    I couldn't tell you. However, check /var/spool/cron for any cron files for evonuke. Look in that cron file and see what is going on.

    For instance, in CentOS and Cpanel 11, my individual user crons are in /var/spool/cron. I can look at a users cronfile and see what type of things are happening.

    It would be interesting to see what is in /var/spool/cron/evonuke

    i check following:
    Code:
    [root@server ~]# cd /var/spool/cron
    [root@server cron]# ls
    b34zdid  d3ldar   mailman  ntapa  persuyw  rootn    t44k8ar
    be97uuir   mahsrg  munin    parsagar  root      lazio
    
    evonuke don't have any cron.
