Questions about two bugs in the cachebench log file

[wangyuyue]

Hi developers,
when I run the cachebench and check the log files, I notice two bugs frequently occur.
First, the eviction success rate in Evict Attempts: 7,105,134 Success: -259625561934544.84% is usually a negative number. So I guess the calculation is not correct.
Second, sometimes the log has missing timestamps. For example, the timestamps are 11:45:18 and 11:46:18, and then directly jump to 11:52:18. This bug is rare, but It would be great to be resolved, as a contiguous log makes performance analysis easier.

Thanks a lot.

Hi, can you share a cachebench config that generates the negative success rate?
