> I tried to send 5000 message to kafka broker using Jmeter ( 10 thread and 500
> messages per thread,one message is 105 byes). After 2100 messages I am
> getting the following exception and I changed buffer size
> (socket.request.max.bytes) value in server.properties file but still I am
> getting same exception. When I send 2000 message,all messages are sent to
> kafka broker. Can you give a solution?
