Today I installed Matlab on the head node of a small cluster. It is running Scientific Linux very similar to CentOS 6.4.

Mathworks uses a jnlp based download agent.

After Firefox just didn't seem to do anything, I ran it from a command line. I got a single GTK error but those are so common I just ignore them. Then it seg-faulted.

After a little reading I found a suggestion to use javaws -verbose, to help track down the problem or so I thought.

Running the exact same command with -verbose (javaws -verbose donwload_agent) everything worked just fine.

I had tried both openJDK 1.6 and 1.7 both got the error.

Any idea why -verbose would fix this?

Thanks,
Joe

A little more information:

The actual error is:



Some googling does show this is not a unique problem and I even found another person for whom adding the -verbose flag fixed his problem (not a Matlab download_agent).
