MySQL Client Error: Connection cannot process a request for Instance of 'PrepareHandler'

[u007]

i think after running the instance for a day, the connection seems to got disconnected.
i suspect there are no mechanism to reconnect.
getting some difficult to identify error:

MySQL Client Error: Connection cannot process a request for Instance of 'PrepareHandler' while a request is already in progress for Instance of 'PrepareHandler'
