IIS Flash Remoting Request Limit introduced with Coldfusion 9?

[ciaranarcher]

Hi all

We've just been our Coldfusion servers from CF 8.01 to CF 9. They are running Win 2008. We ran into trouble on those servers that provide the Flash remoting back-end for a Flex application we provide. 

Once the CF 9 upgrade was complete we noticed that during busy times when many Flex clients were connecting, we appeared to have a hard limit of 25 Flash Remoting Requests running, despite having much higher limits (in fact 150) set in CF Admin. 

Initially we thought that this was an issue with the fact that Blaze DS was now bundled with CF 9 (rather than a separate install) so we decided to roll-back the CF 9 installation. This, unfortunately, didn't work and we were still stuck with out hard limit of 25 Flash Remoting requests.

Then looking at IIS we noticed that the CF9 ISAPI filter was still installed (after we had ran the Web Service Configuration part of the install). That was removed and the CF 8 one was re-run and all of a sudden the Flash Remoting hard limit disappeared. So it seems that it might have had something to do with the wsconfig of CF 9 (C:\ColdFusion9\runtime\bin\wsconfig.exe)

Has anyone else had this problem, or does anybody know of where these hard limits are configured in IIS?

Any and all help appreciated!

Let us know here (and there) if that was the solution for you (and others). Thanks.
