TCP will attempt to resend until the packets are successfully delivered or a timeout occurs. So a packet loss should not lead to an error. The error you see in your log is the queue of unsent events in the client backing up to the point it hits its configured memory limit and then dropping events with that error. Presumably this is due to having to continually retransmit data at the TCP layer...
