502 error on POST

[PipingRockIT-cj]

We are having issue with our .net web app running in IIS where certain post functions are failing with a 502 gateway error and event viewer shows an error (A process serving application pool 'apppoolname' suffered a fatal communication error with the Windows Process Activation Service. The process id was '####'. The data field contains the error number.) We have determined the dd trace agent is causing the problem, as stopping the service or removing the trace agent completely stops the errors. I enabled debug and reviewed the logs but did not see anything that stood out.
