Hi Azat
The behaviour of my program:

1. one thread produce messages , put it in an queue. if queue size change from 0 to 1, write one byte notify message.

2. the libevent event loop(another thread) receive the notify message, begin to invoke notify callback:

  1. drain some messages from the queue

  2. bufferevent_write to write message.

3. write callback

  1. if output buffer size of bufferevent is > 0 ,return

  2.Âdrain some messages from the queue(if any)

  3. bufferevent_write to write message.

 Â4. read callback

    1. try read response. when server send response, it always means the TCP connection will be close.

Can you describe behaviour of the program more?

I.e. when event callback is triggered, after specific timeout?
Does read/write callback triggered before?

Â

Only write callback triggered.Â

Or you can add some logs into you application and post them here.

Also you can enable libevent internal logging with
event_enable_debug_logging().

I will try.Â
