Azat, Yes this happens every time server close the connection. To reproduce i : * start my client (multiple threads but event_base being exclusive to 1 thread handling the events) * start server * generate some requests from client which succeed * stop server * generate some requests where now it loops forever.
I can write reproducer and try it with latest libevent too. In the mean time i have live GDB attached, if you need any info let me know.
