A w3wp.exe process crashes when a performance counter value is requested while the worker process shuts down

View products that this article applies to.

Symptoms

An Internet Information Services (IIS)-based website may crash intermittently because a W3wp.exe process stops in Windows Server 2012 R2 when the operating system or an application tries to access a performance counter value during the shutdown process. This may cause system error events and prevent a graceful shutdown of the worker process.

Cause

This problem occurs because the memory that is allocated to the performance counter is already freed.
