Hi Seth, Are you using streamline in fibers mode for this test? If so it may be worth upgrading to 0.11.x and trying generators mode.
We had a high memory consumption in one of our processes. In fibers mode we had very large oscillations on memory usage with high peaks and it was a bit difficult to tell whether there was a memory leak or not. It looked more like a fragmentation issue that was delaying release of memory because we were getting sudden drops from 1,200MB to 300MB every 10 minutes. In generators mode we got a lower memory usage, a very flat memory curve and no drift at all (no memory leak :-). Memory usage kept oscillating between 210 MB and 240 MB throughout the test.
