Hi, I haven't been able to reproduce this yet. May I know what build configuration you are using?

The UFID is set to opt_dbg_exc_mt_64_shr_cpp17. The build system is GNU Guix. If you search the following build log for starting phase you will see the commands executed during the build.

zhl6k25qlxsb60m5z4342n1jn17pw7-bloomberg-bde-3.110.0.3.drv.gz

Hardware is an AWS r6i.xlarge with 4 vCPU running Amazon Linux 2.

I have now seen errors on case 4 (as above) and case 2. Running the test executable directly so as to capture the verbose output (and ignoring successful results; the failures are highly intermittent):

I think I know the cause of the test failure you're seeing on case 4. However, I can't reproduce the test failure you reported on case 2. One theory is that it's related to the fact that the test driver computes d_startTime with nanosecond precision, but bdlmt_eventscheduler uses microsecond precision internally. If this theory is correct, then if we adjust the test driver so that it truncates d_startTime to microsecond precision prior to passing it to bdlmt_eventscheduler, the failure should not occur.

Can you add the following at the beginning of ChronoRecurringTest's constructor, before the line d_callTimes.reserve(1000);, and check whether it still fails case 2? If so, please show the output under -v -v (that's two -vs, not three).

        if constexpr (std::is_same<CLOCK, std::chrono::system_clock>::value) {
            static_assert(std::is_same<typename CLOCK::period, std::nano>::value);
            const Tp adjustedStartTime = std::chrono::ceil<std::chrono::microseconds>(d_startTime);
            if (veryVerbose) {
                cout << "adjusting d_startTime from " << d_startTime.time_since_epoch().count() << " to " << adjustedStartTime.time_since_epoch().count() << '\n';
            }
            d_startTime = adjustedStartTime;
        }
