Boost Server Stopping on Client Disconnect

[Gary Oliver]

Hardy,

I have been working on several peoples simulators recently and find that when disconnecting a boost client the boost server can stop and not restart again.

I started off assuming it was something wrong with my clients but have confirmed that they are gracefully closing the socket connection.

It seems like there is some kind of race condition that causes the following error anywhere between the first disconnect and the third of a boost client and then the boost server needs starting manually again.

Please note I am using Windows OS'es (tested on 8 through to 11).

Any thoughts?

Hardy,

It would appear when using system.sockets in c# calling a socket.shutdown() causes the issue.

If my app just calls a socket.Disconnect() on closure everything terminates gracefully without the exception.

Does your add-on send the word "exit" and apply a little delay before it actually disconnects?

Hardy,

Oh!  In all the years of writing addons for PSX I have never noticed that section of the documentation!

I will rectify, however it doesn't seem to have caused any issues so far on the main server, however I do run Simstack switch in front of PSX Server which has probably protected it somewhat.

Cheers
