What do error codes mean, e.g. errno=11 #65

recv on socket 14 returns -1 (errno=11) socket 14: 1 ( IPOLLING_READ ) recv on socket 14 returns 20 (errno=0)

Can you share your command line and operating system?

I'm 90% certain this is expected and normal for TCP mode. errno 11 is legacy EAGAIN, which means the socket didn't have any more immediate data on it. This is a benign error - really just a verbose info message. Not an actual error.
