Hi,

we are using SignalR v 1.xx. And sometimes some errors bubble up in connection to Radcompression .

There are others with the same problem:
https://github.com/SignalR/SignalR/issues/1535

Fehlermeldung und Stack-Trace

Fehlermeldung: Microsoft.Owin.Host.SystemWeb: One or more errors occurred.

Stack-Trace: Server stack trace: Exception rethrown at [0]: bei Microsoft.Owin.Host.SystemWeb.Utils.<>c__DisplayClass1.

Is this a known problem?

Best 

Nils

Hello Nils,

The described issue is very strange. We have not encountered it so far and we are not sure what could be the reason for experiencing the problem. Could you please try isolating the problem in a simple example and send it to us. You could open a formal support ticket from your Telerik account and attach a ZIP file there. Thus we will be able to gather more details about your scenario debug the application and investigate the problem.

Looking forward for your reply.

Kind regards,

Hey guys,

I am also having this particular issue and have tried investigating what might be causing the problem. This is what I have seen so far:

It seems that RadCompression is intermittently compressing SignalR's json request string, which I think is being done to the point where certain information needed from the string is missing. I removed RadCompression from the web.config two projects where I was having the error described and have had yet to see another occurrence of the error since that was done about two months ago.  I also found that the page-level RadCompressionSettings attributes won't work in the case of signalR because the request signalR is sending seems to come from code in their SignalR.Hosting.AspNetHandler dll, so the attribute won't help in that case.

Hope this information helps,

Anthony

Hello,

We tried to reproduce the described issue but to no avail. If you can send us a small runnable example and exact steps for reproducing the problem we can debug the application and the RadCompression and find the reason for the described issue. However without runnable example where the problem could be reproduced it is very hard to say what is causing the problem.

Yeah, the error is very hard to replicate...
We get it too in IE10 and FF20 on one machine only...

Hi Joe,

Unfortunately without having a simple runnable example where the problem could be replicated it is very hard to say what the reason for the described issue.  Could you please try isolating the problem into a small example and send it to us. You could open a formal support ticket from your Telerik account and attach a ZIP file there. Thus we will be able to debug the project and provide you with more to-the-point answer.
