FlorianBourniquel commented 6 years ago

How many VRam do you set for your jvm because this is the behavior when java doesn't have enough vram left.

ttben commented 6 years ago

I left the default settings, and started your project from the IntelliJ IDE, so 1/4 or my 16GB memory I guess ?

I started it via the jar file newly produce on mvn clean package and everything seems to work fine

I think u can close this issue.

PS: How much RAM do u think is necessary ?

FlorianBourniquel commented 6 years ago

>= 1Go but the graph library have a memory leak so after a long time you will have this error but normaly it will take hours. Try to add this args -Dprism.maxvram=1G -Dprism.order=sw to your jvm

ttben commented 6 years ago

👍 so nothing to do with the actual ram Thanks!
