@erikzhang would you care to actually elaborate on your problem?

[erikzhang]

I'm using the TCP Driver described in documentation. http://getakka.net/articles/networking/io.html
But sometimes the error log shown above appears on the console.
It seems that the system is attempting to restart the TCP connection actor. But this is supposed to be unexpected, isn't it?

I found you here, @erikzhang....aehauehauea

@Horusiath, It is also described here #3648, I did not see this one before opening. Sorry if it is kind of duplicated.
There are some additional descriptions there. Should I close there and merge comments here?
