Application Pool shutdown due to IIS Protocol Adapter Availability (Technet ID 5138)

Application Pool shutdown due to IIS Protocol Adapter Availability (Technet ID 5138)

  
Hi everyone,

I´ve been detecting frequent application pool shutdowns in our development server. According to Event Viewer logs, this was caused by a series of failures in the process(es) serving that application pool.

Much like the reported warnings posted in topic Application Pool disabled automatically we also detected the following error: A worker process 'XXX' serving application pool 'YYY' failed to stop a listener channel for protocol 'http' in the allotted time.  The data field contains the error number.

Following up on the data field, Microsoft´s Technet article Event ID 5138 — IIS Protocol Adapter Availability doesn´t suggest any other approach than simply restarting the application pool. This obviously isn´t a final solution... anyone with previous experience (or ideas) on this matter? 

Thank you!
