WAS Application pool 'v3.sindiconet.com.br' is being automatically disabled due to a series of failures in the process(es) serving that application pool. A process serving application pool 'v3.sindiconet.com.br' suffered a fatal communication error with the Windows Process Activation Service. The process id was '4492'. The data field contains the error number.

Some consequences like web site down happens and a 503 error are launching in the browser.

I caught up on updates in OS and i have searching for this problems, that let me to do some options like:

• Remove net.tcp, net.pipe, net.msmq, and msmq.formatname bindings


• Install KB2640103 hotfix, that needs to ask for Microsoft Support Customer.

I'm not a expert in Wwindows server, and before to apply these suggestions, i would like to understand the situation and receive more comments.
