Today I experienced first time an Out of memory in P3D v4.5...  it took on my flight with the FSLabs A321 from MUC to ARN all of the 32GB of memory... how is this possible?

Sim crashed with out of memory message.

I did not have these issues since the old 32bit...

Have you disabled your swap (paging) file? That would probably do it.

I think not (page file is set to 32GB), I will do it, but it is strange, so for sure are not the clouds or the FSLabs (because till north of Germany all was fine). Might be something from ORBX Germany North or some airport in that area above which I was flying... 

Normally P3D uses around 6GB on my side, as soon as I get close to 40-60nm from EDDB it rockets up to 32GB... did the flight again, it happened again in the same area.

That did it, now it passed the zone with the problem without issue, thanks for the hint!

I noticed that at that time with page file ON, the reading from C:\ drive was at max also (P3D is installed on other partition). Probably some Windows or something corrupted.. I do not understand.

It sounds like a memory leak. Some running process is not releasing memory back to the operating system after it is done using it. It could be something in P3D itself, the FSL A321, Orbx scenery, or some other add-on running at the same time. Most likely it is something unique to the particular combination of sim/aircraft/scenery you are using. Finding the exact cause could be very difficult.

This is a different problem than the “out of memory” error that can affect FSX and pre-V4 versions of P3D, where the sim + add-ons might simply need more total memory than a 32-bit sim environment is capable of providing.
