[Bug 64756] New: lost samples when doing distributed testing

https://bz.apache.org/bugzilla/show_bug.cgi?id=64756

            Bug ID: 64756
           Summary: lost samples when doing distributed testing
           Product: JMeter
           Version: 5.3
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Main
          Assignee: issues@jmeter.apache.org
          Reporter: chanjarster@gmail.com
  Target Milestone: JMETER_5.3.1

I created a distributed test, prepared 10 remote servers.

A script contains a thread group with 600 threads and 10 loop count.

Theoretically, jmeter should got 600 threads * 10 loop * 10 machine * 9
requests = 540000 samples, but i only got ~ 510000 samples (see attachment)

BTW, if 100 threads, the result is good.

I found that there is a delay between starting remote engine and remote engine
started:

Can you provide:

- jmeter.Log for controller and workers ?
- the output
- What version of JMeter are you using ? 

Thanks
