Since yesterday we started noticing 503 erros in production, where a lot of warnings are stoping the IIS pools.
The erros in Windows Server Event log is:
<code>Exception information:

It seems like it occurs before entering the application code. Maybe a malformed request the client is sending to the webservice, but we can’t capture the request inside the system, because the error occurs before enter the code.
Any ideia about a line we can follow?
