Issue/Introduction

After the .NET agent installation with Sharepoint site, it is generating many different type of errors including error 504. Site also stopped working completely. 

Cause

Looks like the agent is getting initialized too early and thus causing issue with SharePoint.

Resolution

Test with the following properties one by one and then both together.

Test 1)

introscope.nativeprofiler.generic.agent.trigger.enabled=false

Test 2)

The following will tune down the extra instrumentation.

introscope.agent.discovery.autostart.enable=false

Test 3)

introscope.nativeprofiler.generic.agent.trigger.enabled=false

introscope.agent.discovery.autostart.enable=false
