Socket still alive!!
Hi,
I'm investigate about a problem regarding a connection between two server (S1 and S2).
A client software on S1 made a pool of connections on S2; for some reason some connections end but sockets still alive on S2 and not on S1.
I always knew about sockets as a pair of processes; is it possible that just one end of comunication still alive and the other one not?

HP-UX version is B.11.23 U ia64

thanks to all

Indeed, it's possible.
Socket is alive until it's closed.
It's not a communication channel, but kernel api.

It's application's responsibility to close sockets properly.
If one side got disconnected another side expect to have 0 length of read data or failure to send error.

Multicast is another story.
