Multiplayer game kicked out players after being paused for a while (Broken pipe)

[Hans Joachim Desserud]

Happened at the playday yesterday. Played multiplayer with two others, and we decided to take a 5-10min break. As host, I forced pause. A while later I asked if we should continue, but I got no reply. Shortly after that, the other players asked in IRC why they had been kicked. Then I was kicked out as well, with the error "Program received signal SIGPIPE, Broken pipe." which as far as I know means the program didn't receive any input for a while and terminated the connection. Is this a problem when games are left in pause for too long.

We played build16, but the commits doesn't seem to suggest any major changes in the network code since then.

Attached a backtrace. Not sure how useful it is.

Low as this (hopefully) happens rarely.

I faced a similar problem with my dedicated server, thus I took a closer look at it and (hopefully) fixed the problem of the dedicated server as well as this one. In forced pause mode the host will now send a ping to all connected clients every 20 seconds, to keep the sockets up and running.

I will merge the branch to trunk soon.

If the problem reappears, please reopen
