I'm pretty sure that this is working in our test. Please post the exact command that doesn't behave as expected. > Regarding buildup of summary data in memory Summary output size grows linear with simulation duration and would therefore function as a "memory leak" in long-running simulations if not flushed to disk. In contrast, statistic-output uses a fixed amount of memory since it only accumulates in a constant number of variables. Am Mo., 14.
