OS=Windows Server 2003 (Enterprise Edition)

Platform = VMware ESXi 5.0 U3 virtual machine

Memory=6GB

IIS Version = 6

ASP.NET Ver. = 4.0.30319

Effectively when we start AppDynamics Agent everything seems fine with calls coming in and the application works fine. However after 10 minutes , approx, the web site display unable to display page and the above errors are recorded. 

Stoping the service 'AppDynamics.Agent.Coordinator' bring the web page back to life.

Eager to continue testing this great lite tool but need to sovle this rather disappointing issue before proceeding. we are looking to roll out this product to a very large estate of IIS 6/7/8 web sites (excess over 250sites) however if we can resolve this issue we will have to look at alternatives. 😞

Look forward to your response (please feel free to email me as this testing is happening now.)

Can you kindly attach the agent logs and event logs to the ticket. This is will help us troubleshoot this issue further.

Log files added as request. Event logs attached in original Post.

Thanks

Could you please confirm are there any IIS reset or App pool recycle happened during this instrumentation.

Forward fresh set of logs files along with event logs when problem persists. Please let us know if there is any disconnect.

Thanks,

NO. Also there are maybe in excess of 6 web sites being run from this test server and only one website fall foul of this issue.

Hi David,

This is a known issue, Can you try disabling log4net instrumentation and let us know if you are still seeing the issue.

Instruction provided below:

1.) Please add the following line into the "application.config" in the "C:\Program Files\AppDynamics\AppDynamics .NET Agent\Machine Agent\Configuration" directory. (C: or Install Directory)

Line to add:
<instrumentor name="log4netInstrumentor" disable="true"/>

Note: Add this line to the other instrumentor entries in the existing <instrumentation> section

2.) Save the changes

You need to restart the AppDynamics Agent Coordinator service and the instrumented processes (i.e App Agents).

Please let us know if you need any assistance in configuring above.

Regards
Gunjan.
