[IDV #RJN-525466]: IDV: Could not create a graphics configuration and java heap space error

> 
> Hello,
> 
> I have a couple of questions for which I am aware antecedents are
> discussed on your forum, support archives and documentation, but they
> unfortunately did not bring me much further with my issues.
> 
> I succeed in running IDV 2.8 and 2.9 locally on a 64bit linux box
> operating under openSUSE 11.1 and equipped with an NVIDIA GeForce 7300
> graphics card with a 2.1.2 NVIDIA 190.42 driver.  I have 4 GB available
> memory and increased memory available to java in runIDV to 2560m.
> Still I have memory problems (java heap space error) displaying
> cross-sections or isosurfaces of  3D data fields taken out of a 1.7 GB
> netCDF file (the field itself takes up a fraction only of that space).
> Is this normal and is there a workaround without decreasing the domain
> size or resolution (via region or stride)?

When you are displaying the cross section or isosurfaces of 3D dataset, 
depending on the size of each dimension, it could
consume a lot memory. If it is a large grid, you would be advised to subset it. 
 See the following information:

In some 64bit machine, remotely running the IDV may have some issues. The other 
option 
is VNC.
