knime 3.1.2 hangs in startups

Hello everyone,

I just downloaded knime 3.1.2 in my linux box (ubuntu 16.04) with an Intel i7 and 8GB RAM. The first time it took a long time to start. When I tried to open a the local example workflow it took above 2 minutes to actually open it.
Reading in it the forum I found a that I should increase the heap size. I put it in 3GB (I have 4GB of free RAM) but that does not solved the problem. In fact if I want to create a new (blank) workflow it takes long enough to cancel the operation (which also fails), which forces me to kill the task from the OS.

How can I make knime to run faster? Anyone else with the same problem?



This is a bug in Ubuntu, see
