Description

The jvm process defaults to allowing a process to take a percentage of physical memory. In one particular case, 6GB of virtual memory is allocated although <200MB of memory is actually used by the watchdog and master java processes. For processes with low memory requirements we should set -Xmx to a reasonable value (256m?)
