DEFAULT FORMATTER CRASHED error

[abhaikollara]

I tried running ./emqtt_bench conn -c 50000 -i 10 on my local machine. And after about 1000 connections it keeps showing

connected: 1003DEFAULT FORMATTER CRASHEDDEFAULT FORMATTER CRASHEDDEFAULT FORMATTER CRASHEDDEFAULT FORMATTER CRASHEDDEFAULT

I noticed a similar issue #63, but my Erlang version seems to be up to date (Erlang/OTP 22). Should it be exactly 21.2 ?

P.S: I'm running the broker as a docker container.

we are running ./emqtt_bench pub -V 3 -c 100 -I 10 -s 600 -p 1883 and getting the same issue. Versions 1, 2, 3, and 4 start spitting DEFAULT FORMATTER CRASHED with an occasional

sent(70000): total=555588, rate=7987(msg/sec)
pub(70001): total=555610, rate=7994(msg/sec)

What does this mean? We would ideally like to have many more connections/messages sent.
