    Here are the steps:

    1. download and install the package

      tar zxf lsws-4.1.13-ent-x86_64-linux-dbg.tar.gz​
      cd lsws-4.1.13​
      ./install.sh​
      Note: choose 'U' for upgrade when prompted and default for the rest.​
    2. remove old core files
      rm /tmp/lshttpd/bak_core/*​
    3. send new core (or new /etc/csf/suspicious.tar) to bug@ when it generates.

    run "top -c":
    I killed the process by
    #kill 27128

    like I did last time. please see if email still coming in.

    please try to upgrade to 4.2.2 manually. it fixed a few mod_security bugs and likely including yours.

    #cd /usr/local/lsws/admin/misc
    #./lsup.sh -v 4.2.2

    this email was sent out 1 day ago, it's about bug for lsws 4.2.1.
    since you have upgraded to 4.2.2, should be no 4.2.1 related bug report any more.
