             Summary: Research behavior of fork with ProcessBuilder on modern JVMs
                 Key: WFLY-3202
                 URL: https://issues.jboss.org/browse/WFLY-3202
             Project: WildFly
          Issue Type: Task
      Security Level: Public (Everyone can see)
            Reporter: David Lloyd


Right now our Process Controller exists for two primary reasons:

# fork() misbehaves for large processes on some OSes, causing leaks or crashes
# if the HC crashes, the PC can respawn it

We have never (afaik) seen #2 happen.  We need to verify whether #1 is still true on modern JVMs on the following operating systems:

* Linux
* Solaris
* IBM OSes
* Windows
* BSDs
* Mac OS X

Test by creating processes with large heap and lots of concurrent file descriptor activity while forking to see what happens.
