I have noticed that sudo time ./cyclictest -S -D 30 properly completes the test and exits in 30 seconds. However, doing: sudo time ./cyclictest -S -D 30 -M the test never stops, I have to control-C out of it. Is this intended behavior? The man page did not say anything about this. I would like to use both -D <many_hours> and -M together. Thanks for any comments.
