I have a TomCat 8.5.23 service running on a Windows 2008 R2.  It is 
currently running a third party web commerce application.  It will run 
great until randomly one day the application will stop responding.  When 
you try to go to the application URL it sits and spins.  I look at the 
catalina log and found the below errors at the time it stop responding. Is 
this a tomcat configuration issue or application related.

I see three specific warning/severe messages in Tomcat.

Error one:
02-Nov-2017 10:03:23.787 WARNING [http-nio-9080-exec-402] 
Unable to find component with ID searchPattern in view.

Then right after there is a severe message error 2:

02-Nov-2017 10:03:23.896 SEVERE [http-nio-9080-exec-455] 
org.restlet.engine.http.adapter.ServerAdapter.commit An exception occured 
writing the response entity
 org.apache.catalina.connector.ClientAbortException: java.io.IOException: 
An established connection was aborted by the software in your host machine

Then the warning messages constant all the way down until this all the way 
down until we had to reboot the service because of no response. 

02-Nov-2017 10:03:23.896 WARNING [http-nio-9080-exec-455] 
org.restlet.engine.http.HttpServerHelper.handle Error while handling an 
HTTP server call:
