When trying to view a Graph as generated by the depgraph-view plugin, an exception (below) is thrown due to memory constraints.

On research there may be a correlation between this error and the forking behaviour of the plugin, as based on the following stakoverflow article: http://stackoverflow.com/questions/1124771/how-to-solve-java-io-ioexception-error-12-cannot-allocate-memory-calling-runt

The machine I am running on is close to capacity, but I would not expect this plugin to exceed the limitation;

Reduced priority from original as this does not block our ability to use Jenkins itself, only the plugin on this instance. My other standalone Jenkins installation works fine.

I think you are correct and this error is related to the forking behaviour of the vm. Since I am using the default Launcher from the Jenkins projekt, I believe that this is the default behaviour. So if this should get fixed you probably should open a bug against the core or try asking on the mailing list.

I have added "core" as the component which this issue relates, and "auto assigned" the issue, but I'm not sure where to go with this particular issue to get some resolution, or at least a workaround.
