Hi, I have a pool of threads that needs to send messages to a zmq socket. I was creating the socket, connecting, sending the message and closing it for each message, but it is for sure not an optimal usage of resources, since if I create/close sockets too fast, zmq is not able do release them as fast and I get the error: "too many open files (signaler.cpp 330)". Since I have no control over those threads, I'm about to try the following solution:
1 - create a pool of connected sockets (REQ, inproc) 2 - when a client thread wants to send a message, it grabs a socket from the pool 3 - the thread performs a send/recv 4 - the thread releases the socket (which will be again available in the pool) The question is: what should I do to make this multi-threaded usage of sockets safe? Is it enough to guarantee that multiple threads do not perform send/receive simultaneously? Thanks, Thiago
