Subject Re: Exception in Cayenne Modeler, heap blows up

Yeah, I think attachments are stripped from the list messages automatically on the server.
Are you using the Windows or Mac Modeler? Both are pre configured to run with 0.5 GB of heap
space, but maybe -Xmx is getting lost along the way.

I'm doing. I haven't seen anyone post with attachments so far on this userlist so I don't
