Connection to the Chat Server is lost - CS implementation

Reply Quote

We are evaluating Cute Chat. It worked on my development machine. I deployed it to our test server and it worked. We pushed it to our "Beta" live site and it crashes.

We have the same error coming from Messenger and Chat:

Please wait, connecting to server...
Connected!
The connection to the chat server is lost.
Please wait, connecting to server...
You are already logged in this chat application. A new connection cannot be established.

Does anyone have an idea what might be going wrong?

Thank you,

Rick

Please hold the Ctrl key then double click the chat window. A debug window will appear. Please post the detailed errors of the debug window.

Nice trick! Here are the debug results:

turn chatui.js.aspx-CHATUI_DEBUG off to hide this frame for default. use CTRL+DBLCLICK the MessageList to show or hide the DebugList

TRACE : Connecting..

TRACE : Connect_Callback . READY ,

TRACE : _Sync_Return:NOCONNECTION:conn-_104

TRACE : Connecting..

TRACE : Connect_Callback . IDEXISTS

What is weird is that if you are able to time it right and send something in that second that it says Connected!, you retain the connection and everything starts working.

Here is a trace where I hit the connect button and then typed something in and hit return while it still said "Connected!". After this, I retained the connection:

Hi RickPost,

Maybe your server is running web garden.

Please configure the IIS, and set the processes count to 1.

Keep me posted

Regards,

Ken,

Thanks for the idea, but I checked and the max processes is already set to 1.

Rick,

Are you using load balancing?

I was wrong about Web Gardening. I checked with the webmaster and the max helper processes are set to six. I must have been looking in the wrong place.

I changed our test server to have six processes and that screwed up chat. So that appears to be the problem.

My question is, is there any way around that? Our web master doesn't want to change it. If we have web gardening, we can't have chat?

There was also a question about load balancing. If we have load balancing, we can't have chat?

I thought this was a scalable application.

Thanks,

Rick

Rick,

Correct. Cute Chat doesn support web garden because each web garden is it's own process.

So that's it then? We use web gardening, so we can't use your product - end of discussion?

You cannot use Cute Chat if you are using web gardening.

Of course I don't know the internals of your code, but from playing around with it, it seems to me that it wouldn't be that hard to fix.

After it says "Connected!" and before it says "Connection to the server is lost", if you manage to type in a message and send it during that window. It seems to retain the connection and work fine after that. Perhaps you need to add something to your application to mimic this behavior.

We have a quad-processor server, which is pretty common these days. If we don't use a web garden, then we are not taking full advantage of the multiple processors.

Do you have any plans to address this issue, or are you going to limit yourselves to the single-processor server market?

ASP.NET is a multiple threads environment , It still use all CPUs when it do not use web garden.

Do you have a citation to back this up? I'm no webmaster, but almost everything I have read seems to indicate that web gardens improve the performance of mutliple-processor servers.

There was one post I read that seemed to back up what you said, but it was just an opinion.

I'm still skeptical because you do not seem willing to try to make your product compatible with web gardens and you are quick to dismiss them. Also, I am a little concerned with the quality of your technical support since the "live chat" personnel seemed to be clueless.

I don't mean to be insulting, but we have a live site that we do not want to compromise by including a "not-ready-for-prime-time" third-party product.

Personally, I like your product and I have it all configured to integrate with our website, but our webmaster does not want to turn off web gardens. If you can't provide me something that I can use to convince our webmaster that we do not need web gardens, then we will not be able to use your product.

Hi,

We have added your requests to CuteChat version 5 and have implemented the web garden support.

CuteChat version 5 would be released soon.

However to support web garden, you need to set web site trust level to be Full or High.

It's the best we can do.

Hope it helps.
