I guess you don't have much RAM either and are running a 64bit Java which occupies more space than a 32bit Java. I don't think there is anything you can usefully do about it without restoring the page file to a larger size. Ideally you want both a RAM and HDD upgrade.

Click to expand...

I see, but...



I guess I perhaps have to use 32 bit, im using jdk 11.

I also noticed something.

When b4j is opened without a project opened.



After opening the project (not pressing run)



This is still fine...so im baffled at what happens when clicking run for a need of such a large amount of memory.

Are you running lots of things in background ( web browser pages etc)?
Try closing some down to free up 'real' memory.

As @agraham said the more memory the smaller the swap file becomes (mine is managed by Windows)

Yippie!!!!

I have installed java jdk for 32 bit, set the swap file to 4GB and the memory allocation error is no longer showing and my app ran well. Thanks guys.



I will ensure that most back-ground services like the sql server that im not using and dont know who started it, are closed.
