The class represents an asynchronous state object that is used by asynchronous transport agents.
Assembly: Microsoft.Exchange.Data.Transport (in Microsoft.Exchange.Data.Transport.dll)
Thread starvation can occur if the code that is executing asynchronously takes a long time to finish. Therefore, it is important to monitor the thread pool and reuse threads that are allocated to instances of your agent.
If thread starvation occurs because of an asynchronous agent, the Simple Mail Transfer Protocol (SMTP) service may stop responding to incoming connection attempts.
You should log an error to the event log if thread starvation occurs. Logging the error to the event log enables administrators and applications that monitor the event log to find and take action on the thread starvation.
