On a Windows workstation running OWB, the default maximum JAVA memory that is allocated for Open Workbench (OWB) is up to 500MB. You can modify the workstation's Windows registry to override the default memory allocation. This can help when running into issues saving large projects back to Clarity PPM.
When saving a project back from OWB, an error such as this one may be thrown:
Unable to save project CA PPM\<projectid>. Connection reset.
