App hang and pulse logger stops

Hi Morris,

I've tried running with the flags you mention but it all stops producing
text when the application hangs and there's no information remaining which
would tell me why the application hangs.

I've also tried using the apps you talk about (jstack and visual vm) but I
can't make sense of the information they present.

The app that hangs is modellus - and the file that
makes it hang is attached (you have to wait a while after opening the file
until the app hangs).

Can you give me some more help, I'm still not aware of what could cause

Thanks, best regards,
