Java Heap Error

Hi Kilian

When i try to save the workflow i get java heap error. I have also changed the following in Knime Configuration



Even after changing the settings i face the same issue. Please guide me with a turnaround.

XX:MaxPermSize shouldn't be set that high. Set it to 256m (permanent generation), thats enough. The -Xmx2G setting (heap) is fine.

More detailed explanation:
The problem is, that the PermGenSpace is part of the heap (the permanent generation). If you assign 2048m (=2G) to the MaxPermSize then it takes the complete size of the heap (which is defined by -Xmx2G) and KNIME has no chance to allocate any memory in the heap.

I hope this helps.
