Research behavior of fork with ProcessBuilder on modern JVMs ------------------------------------------------------------ Key: WFCORE-1146 URL: https://issues.jboss.org/browse/WFCORE-1146 Project: WildFly Core Issue Type: Task Components: Domain Management 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.
