Question

ColdFusion11 to IIS communication stopped working

Installed ColdFusion11 and IIS8.  And the site is configured on IIS8, site working fine. But all of a sudden it started giving Error 503, verified the services it was running, log doesn't not describe any error. Restarted the ColdFusion Instance but no use the site still doesn't respond.

    We have 4 ENT servers (CF11) behind an F5. We're having random issues where the CF application pool shuts down out of the blue.  It generally points back to the isapi_redirect.dll

    Here are the details:

    Faulting application name: w3wp.exe, version: 8.5.9600.16384, time stamp: 0x5215df96

    Faulting module name: isapi_redirect.dll, version: 1.2.37.0, time stamp: 0x532bd775

    Exception code: 0xc0000409

    Fault offset: 0x0000000000045c64

    Faulting process id: 0x1b1c

    Faulting application start time: 0x01d3ba23973c569c

    Faulting application path: c:\windows\system32\inetsrv\w3wp.exe

    Faulting module path: E:\ColdFusion11\config\wsconfig\1\isapi_redirect.dll

    Report Id: daef8fd0-2616-11e8-8121-005056a85183

    Faulting package full name:

    Faulting package-relative application ID:

    it will throw off 4-6 of these rapid fire then the application pool stops.

    Thoughts?

      Please note you would start your own thread. However, the issue is most likely you need to tune the Tomcat/IIS connection properties in worker.properties.  See this extremely helpful blog post by Anit to learn how to tune the connector properties.  https://coldfusion.adobe.com/2014/05/coldfusion-11-iis-connector-tuning/

      I create a "Failed Request Tracing Rules" in the IIS Manager to capture some information.

      Have you checked to see if the IIS Application Pool for the IIS Site is running? Sometimes the Application pool can crash due to performance tuning issues.  If it has crashed, restart the Application Pool. From there we will have to look at tuning the Tomcat/IIS connector properties.

      Okay, lets check the basic things.

      1. Is the jakarta alias still configured? It should alias to the [coldfusionroot]/config/wsconfig/[magic number].  If ColdFusion connectors are configured for all sites the 'magic number' is usually 1. 
      2. Make sure that the above folder is still in place.
      3. Make sure the Isapi Filter 'tomcat' is still configured in IIS for this site.
      4. Check to see the Handler Mappings for ColdFusion are still configured in IIS for this site.
      5. Check the web.config file. Some settings are stored in there. If the file was overwritten or removed and ColdFusion specific settings got lost, that can cause this issue.

      What do the Coldfusion logs say?

      Error 503, ColdFusion doesn't have any particular logs related to that.
