OutOfMemoryException while building a project

Unfortunately, since a few days NCrunch fails to build the same project due to an OutOfMemoryException:

Any hint would be greatly appreciated.

Hi,

Thanks for sharing this problem.

Do you see this consistently? Or does it happen after a while?

Does changing the build process CPU architecture to x64 make any difference?

Hi Remco,

thanks for your super quick reply. In the meantime I have rebooted my machine which solved the problem for now. Therefore I guess it happens after a while.

Thank you for the hint regarding the build process CPU architecture - I will try changing it the next time it happens to see if it makes a difference.

Kind regards,
tjahn

Hi Remco,

changing the the "build process CPU architecture" solved my problem reliably, thanks again!

Kind regards,
