B4J Question [SOLVED] B4J and Paging Files & Java VM Memory.

[Mashiane]

Ola

My HDD is very small, and I had just noticed that the pagesys file, which is managed by windows was taking 16GB and decided to set it to 2GB. Now I cant seem to run b4j. Is there a way to set the Java VM not to use so much memory? I have not set anything on my app for VM management just basic usage.

Thanks.

I just set this to 2000MB

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.

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.
