IIS 8.5: A process serving application pool '<ApplicationPoolName>' suffered a fatal communication error with the Windows Process Activation Service

I am running an ASP.NET MVC application on IIS 8.5.9600.16384 under Windows Server 2012 R2 Standard. Sometimes I get below error in the event log that makes my application not responding for a while.

Event ID 5011 - Source: WAS

A process serving application pool '' suffered a fatal communication error with the Windows Process Activation Service. The process id was '1668'. The data field contains the error number.

My website uses Web Garden and its application pool is set to 4 worker processes and using mode StateServer. Also application pool identity is set to a domain account.

ASP.NET State service runs in the same machine where my site is published.

Any ideas about what could be the problem?
