comment Memory consumed by NMaximize with NDSolve
Have you tried it with a fresh kernel? This happens when I start a fresh kernel and run the following 3 lines of code: f[x_?NumericQ]:=……; memInit=……; ListPlot[……

comment Memory consumed by NMaximize with NDSolve
Furthermore, NMaximize seems not to play a role in the memory consuming. (ListPlot@Reap[Do[f[t]; Sow[MaxMemoryUsed[] - memInit], {t, 100}]][[2, 1]] shows similar result. ) Then, let's wait for someone else to answer your question :D (The memory management behind NDSolve is so complicated that it's beyond my reach. )

The WorkingPrecision -> 1 method is interesting! And I take the liberty to add some further exploration to your answer, feel free to undo it if you don't like it.
