WARNING (MainThread) [hbmqtt.mqtt.protocol.handler] BrokerProtocolHandler Unhandled exception in reader coro: IncompleteReadError('0 bytes read on a total of 1 expected bytes',)

Hi everyone,
I updated ha to the last version0.86.4 and looking at the log file I’m still having this issue:
2019-01-29 21:26:09 WARNING (MainThread) [hbmqtt.mqtt.protocol.handler] BrokerProtocolHandler Unhandled exception in reader coro: IncompleteReadError(‘0 bytes read on a total of 1 expected bytes’,)

Consider that i have 10 arduinos that every minute send readed data to ha, so my logs are full of these warning.
What Is wrong?

I’m getting them to so I will switch to mosquitto until hbmqtt is fixed.

My log was full of this error and It’s happened that after 3-4 days of work home assistant freezed.
I migrated to mosquitto broker and now everything works properly.
I’ve 8 arduino sensors connected
