Can't generate histograms on the assertion_bucket error when running example about graphql-bench

[coco98]

@0x777 I ran this again and got the same error, but one data point came through.
How should we proceed? Can you describe the source of the error so that I can get someone from the team to follow up with wrk2?

[0x777]

This looks like an assertion failure in wrk2. I've encountered this once but couldn't reproduce it. We should raise an issue with wrk2 (https://github.com/giltene/wrk2/issues).

I ran into the same problem. This issue in wrk2 was raised #2 and hinted at a clock synchronization problem. I used the trick described here docker/for-mac#2979 to disable the OSX VM's ntp service docker run -it --privileged --pid=host justincormack/nsenter1 /bin/sh -c 'kill -9 "$(pidof sntpc)"';.

After doing this the problem disappears. I expect that this won't survive an osx restart.

Hope this helps
