Hello guys,

I'm having some issues with a ticker being controlled by the API and using the RPC-server. I've copied most of the demo Ticker-project, except it's only one ticker instead of 2.

I have ticker which is on a production which is 24/7 on. However after some period of time the ticker stops working.

No more messages are being displayed and the Debug Monitor gives the error: The RPC server is unavailable.

The only solution is to close and restart the XPression.

Any ideas on how I can solve this issue or at least try to capture it in my controlling software?

This is an API app that you have built in house?

Which demo ticker project are you referring to?

What version and build of XPression are you running?

What is the RPC?

#XPression

Hi Garner,

The application has been built in house yes.

The demoproject I'm talking about is the NewsTicker-CSharp project which was made available by Ross.

The version of XPression is 3040.

The RPC is some sort of engine that returns the statuses of the Xpression I think.

#XPression

What does RPC stand for in this situation?

#XPression

Hi Garner,

I have no idea what RPC stands for. It is an integral part of XPression. As far as I understand it, it checks the onairstatus of the scene which is on air in XPression and returns that state to the API.

However, I can't find any reference to the RPC-server in the API. The only way that I know of the existence of the RPC-server, is because the Debug Monitor is displaying error-messages about it.

Haha! I've never heard of it before - but I've only dabbled with API apps :)

I'll see if I can find out what it is - but maybe someone else will comment in the meantime.

How long is the ticker running before you get the error? Does it stop working after a regular/constant amount of time?

#XPression

Well before a few weeks ago I never heard of it too :-)

There's no constant in the errors. I've had it happen to me after running for 36 hours continuously but also after about 5 hours. So there's no constant. I've been testing it on and off for the past few days and I haven't had any errors so far. I did change the way the application is fetching the information to put in the ticker to make it less stressfull for the application but I'm not sure if that has anything to do with it.

Tomorrow we're going on air again for a non-stop period of 7 days so I'll find out soon enough if it's more stable now.

Kenneth,

Does the sample Newsticker show the same issue for you, or does it work correctly?

#XPression

To be honest Brian, I haven't tried it out with the sample NewsTicker yet, however the code is almost an exact copy paste. Except for the fact that I only have one ticker instead of two in the demo application.

Also the initialisation of the tickers has been put in a separate function instead of under a button.

But other than that it's an exact copy.

Cheers,

Kenneth
