ZeroMQ hanging after sometime

Since some time can’t connect on zeromq dealer until patch reload anyone have the same?

chatted with antokhio, this happened on a somewhat iffy wifi network when the dealer was completely idle for about an hour or so.
once the dealer was supposed to send again, it didn’t send, and even disabling and enabling didn’t help.

I suggested disabling the Dealer when not needed, or sending some kind of heartbeat message periodically so the tcp session is not killed by windows.

Also, KeepAlive and Linger with super low timing can prevent the complete lockdown of the port anthokio experienced.
