How to force Mathematica to clean up the cache
The idea is to run the memory leaking code in an extra kernel and restart that kernel every once in a while. … Here is a simple example based on your minimal working example which demonstrates the idea and shows that the master kernel will not accumulate any memory:
LaunchKernels[1];
Print[MemoryInUse[]];
calcsPerKernel …

Does parallel programming use up large quantities of memory in Mathematica?
I have put some code in between the different parts so that you can check that the memory consumption is really what I am claiming (or see if that's not the case for you, which I can of course not exclude …

Is it possible to force ParallelDo to periodically close and launch subkernels?
Here is some code, not very elegant but should work and hopefully is easy enough to understand so that it probably is good enough as a starting point:
numkernels = 2;
numcalculations = 10;
maxcalcsper …

Memory Problem with Modules and NDSolve
It is a little known fact and probably not well documented, but since version 9 one can use just strings as variables (dependent and independent) in NDSolve, which in this case helps to solve the memory … For me this function does not leak any variables anymore and I think should be free of memory leaks as well. …

Notebook cells space on disk profiler
The code below does not exactly what you have asked for, but it should contain the relevant stuff. To create an index ordered by cell sizes I think it would be easiest to set CreateCellID to True for …

Notebook cells space on disk profiler
Note that the code which adds and removes the cell tags does copy the complete content of the notebook into kernel memory, which might fail for huge notebooks. … While that would be more memory efficient, it might be much slower. …
