I'm curious,   if I render out a scene on my meager "farm" (4 nodes including the local machine) with a pass limit of 1000 my ram (64GB on the host machine) slowly creeps up in usage,    I'm now at  ~450 passes and my performance monitor shows around 52% memory usage.    When I have just let the thing run overnight cinema 4d will crash close saying it's out of ram by the time it starts getting close to 1000 passes.   I'm not sure why this is,   it doesn't seem to happen when I render locally.   The host machine is only used for C4D,   should the ram slowly fill up while rendering?   Or is there a slow memory leak somewhere?

Just in the course of typing this message it's it's now @ 53% at 480 passes,  which means it could never make it to 1000 passes at this pace before the memory is filled and C4D crashes....   When I first started monitoring it at like 200ish passes it was in the 30% range.  My scene isn't crazy big or anything,    Not sure what's going on,  or if this is the expected behavior.     

I don't have any other programs running,  just Windows 10 OS.

What are you rendering that requires 1000 passes?

It's an entertainment scenic design concept with a handful of theatrical moving lights with a volume material applied to a cube.   The number of passes is mainly to clean the noise from the beams of light.
