Socket won’t send data after blocking queue .take()
Edit: I’ve found the problem ( see answer below ) I’m trying to write an Android application to send data to a running termux instance via TCP.

Java Implementing a Client Server Model (Using TCP) and sending a IP address from server and Printing it out on Client

If a peer client disconnects from a server could we just ignore the socketexception at the server side?
I have a server which accepts input from client; it reads text input from client and processes it in some way(each new connection is assigned a thread also).

So basically this exception is an indicator that a client was

Efficient way to extract protocol data units from tcp byte stream

In both cases I was unhappy with the implementation of the communication, since I couldn’t come up with an intelligent, non-verbose and object-orientied way of writing and especially parsing the bytes. For writing I had something like That was acceptable to some extent,
