    This is a fresh cPanel installation, which is about 4 days old.

    Data has been migrated over from an old cpanel server using the Transfer Tool.

    I am now randomly seeing various processes, which indicate as if root is running a command.

    Eg:

    uptime
    grep "A"
    ifconfig
    echo "find"
    su
    sleep 1
    route -n
    netstat -an
    cat resolv.conf
    ls -la
    ifconfig eth0
    top
    who
    w


    Each process comes up one by one.

    When I kill the command, another of those commands comes up.

    These commands claim to be using upto 40% of CPU on an average.

    STRACE doesn't show me anything I can understand. The paths shown in strace are non existent.

    Example of Strace output:
    Code:

    What could be the issue?
