After long-running, the number of executions per second becomes 0.

I used 5 threads and they were running fine at first, but after 40 minutes there was a problem.
Execs/s becomes 0.
Why???

My command line:

It seems all of your samples got discarded
samples: 65 (65 discarded)
The samples can currently be discarded for 2 reasons:
causing too many hangs (over 1 percent of runs cause hangs) or causing too many crashes (over 2 percent of runs cause a crash, meaning most likely that the sample itself is actually crashing unrelialy).
Most likely, in your case, it's the issue with hangs so I suggest increasing the timeout.
If that doesn't work, you can adjust acceptable hang/crash ratios in https://github.com/googleprojectzero/Jackalope/blob/main/fuzzer.cpp#L42
