            Bug ID: 237715
           Summary: maxproc needs a default value
           Product: Base System
           Version: 12.0-RELEASE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: conf
          Assignee: bugs at FreeBSD.org
          Reporter: stefanrink at yahoo.com

Creating a shell file with something like $0&$0& will kill any FreeBSD machine
with the default configuration. (Also kills the host when you try this in a
jail)

In bash;
:() { :|: & };:

There should be at least some default value set for maxproc in login.conf,
unlimited is asking for trouble. :-)


Be careful with this, it takes down your machine hard and only recovery is
power cycle or hard reset.
