    using latest version of litespeed I tried changing default action for modsecurity blocking FROM:



    log,drop,msg:'globalblock' (this is what it was originally)

    this caused the webserver to crash as soon as i triggered a block rule (so all websites stopped working) tested this 3 times

    only fix was rebooting the server

    the crashes only occured after modsec rules triggered, not as soon as the change was made

    I could not make it crash by changing "deny" to "drop".
    Do you get core file under /tmp/lshttpd/bak_core/ ?
    Please install gdb to check the core file with gdb.
    If you set admin's email, you will get email bug report for the crash.
