[Dart] Server Coverage dies, not enough memory?

[Blezek, Daniel J (CRD)]

Ken, et. al.,

  Java has a strange idea of how to use memory.  It will not allocate up to the physical limit of the
systems memory, instead it defaults to 128M.  So the solution is to use a java -X flag to give java
more memory to play around with.  I was hoping we wouldn't have to face this bugger just yet, but
here it is.

P.S.  I'm out of town, so I can't fix this.  I also suspect that it is platform dependant...

I've been noticing that the generation of the coverage html pages
seems to die now and then. I checked on the Server and the
CoverageLog.xml file is fine (big, but fine). The individual web pages
seem to be generated up to a point at which it stops. For example, in
VTK ringworlds coverage everything is fine until vtkTubeFilter.cxx
where it stops right in the middle of the file. The XML is fine as far
as I can tell but the resulting files are not. This is the error...

It looks like Java is running out of memory. The input file is about
20 Meg and the machine has 384 Meg of physical memory plus some swap.
I'm not sure how java is being started. Do we need to increase the
heap size in java? How much memory do we need?

Thanks
Ken
