TomCat 8.5.23 application not responding
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] com.sun.faces.renderkit.html_basic.HtmlBasicRenderer.getForComponent Unable to find component with ID searchPattern in view.

Re: TomCat service is running but not responding
First I notice that we are not able to get to the app through the browser. The browser will just spin. Then I try to get to the TomCat host manager and never get the login box and it just spins. If I restart the TomCat service then I can log into the host manager but not able to reach my app through the browser. If I reboot the whole server then I can access tomcat and my app. I see this error alot before I get the warning messaged and then server messages 26-Oct-2017 09:02:57.481 INFO [http-nio-9080-exec-33] org.restlet.engine.http.connector.HttpClientHelper.start Starting the default HTTP client 26-Oct-2017 09:03:00.820 INFO [http-nio-9080-exec-32] org.restlet.engine.log.LogFilter.afterHandle 2017-10-26 09:03:00 172.16.2.226- 172.16.2.2269080GET /WebSmart-api/categoryList application=b2b&version=1&lang=en_US&securityToken=guest&url=dsgweb.dsginc.biz&accountId=024617&userId=LLEMKE&catalogName=Customer&categoryOnly=Y&categoryNumber=0&numberOfLevels=2 200 - 0 5232255 http://dsgweb.dsginc.biz:9080 Restlet-Framework/2.0.7 - 26-Oct-2017 09:03:00.820 SEVERE [http-nio-9080-exec-32] 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 26-Oct-2017 09:49:57.993 WARNING [http-nio-9080-exec-29] org.restlet.engine.http.HttpServerHelper.handle Error while handling an HTTP server call: 26-Oct-2017 09:49:57.993 INFO [http-nio-9080-exec-29] org.restlet.engine.http.HttpServerHelper.handle Error while handling an HTTP server call java.lang.IllegalStateException: Cannot call sendError() after the response has been committed at org.apache.catalina.connector.ResponseFacade.sendError(ResponseFacade.java:457) 26-Oct-2017 09:49:57.977 INFO [http-nio-9080-exec-29] org.restlet.engine.log.LogFilter.afterHandle 2017-10-26 09:49:57 172.16.2.226- 172.16.2.2269080GET /WebSmart-api/categoryList application=b2b&version=1&lang=en_US&securityToken=guest&url=dsgweb.dsginc.biz&accountId&userId&catalogName=master&categoryOnly=Y&categoryNumber=0&numberOfLevels=3 200 - 0 1261011 http://dsgweb.dsginc.biz:9080 Restlet-Framework/2.0.7 - 26-Oct-2017 09:49:57.993 SEVERE [http-nio-9080-exec-29] 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 at org.apache.catalina.connector.OutputBuffer.realWriteBytes(OutputBuffer.java:356) Darin Bolken | Programmer/Systems Support Dakota Supply Group | P (701) 237-9440, Ext: 8878 | F (701) 237-6504 2601 3rd Ave N | Fargo, ND 58102 dakotasupplygroup.com From: André Warnier (tomcat) To: users@tomcat.apache.org Date: 10/20/2017 09:48 AM Subject:Re: TomCat service is running but not responding On 20.10.2017 15:46, dbol...@dsginc.biz wrote: > I have a TomCat 8.5.23 service running on a Windows 2008 server.

Under Windows, assuming the default installation as a Service, all of tomcat should be under one directory (assuming the default again, something like "Program Files / Apache .. / tomcat"). Locate the subdirectory "logs" under that, and find the recent files. That is what you should look at, first of all. All "events" there have a date/time stamp, so you should locate something around the time when tomcat "stops responding". If you find such lines with the prefix "warning" or "error", copy and paste it here for someone to have a quick look. Then also tell a bit more about the "stop responding" aspect. What exactly happens when you try to access tomcat, in the browser ? Are you not getting any answer at all, no mater how long you wait ? Are you gettin an error page ? Are you getting a blank page ? Note that this list strips most kinds of attachments, so it is better to copy and paste whatever text you get, directly in your messages to the list. - To unsubscribe, e-mail: users-unsubscr...@tomcat.apache.org For additional commands, e-mail: users-h...@tomcat.apache.org
TomCat service is running but not responding
I have a TomCat 8.5.23 service running on a Windows 2008 server. The service would be running fine but it periodically stops responding until I reboot the server. I tried restarting the service but it does not always respond again. I am not sure what logs I can look at or if it is the app that I am running on the service. I looked through the Wiki but with no luck.
