Thingworx HA Primary server Tomcat stopped(Tomcat version 9.0.35)

Hi,

 

I have configured Thingworx 8.5.1 with HA Configuration.

Observed primary Tomcat was stopped and pointed to secondary server. I did not get the reason why Tomcat stopped. Also, verified system is not rebooted during that time. I have observed below errors on "tomcat9-stdout" file. Is Tomcat stopped because of below errors? Do I need to verify any other files in Tomcat logs?

Hi vi1!

 

Please check your Zookeeper instances if they are running. You can just run ./zkServer.sh status

Hi @vi1.

 

Have you taken a look at the ThingWorx logs located at \ThingworxStorage\logs?  This would be the best place to start in troubleshooting the issue.  If it does appear to be a Tomcat issue, you could also check the tomcat9-stderr log.  The warning you found in the stdout log would not have caused the failure.

 

If you can provide the logs, we'll be happy to take a look.  A case may be needed, however.

 

Regards.

Hello ,

Thank you for response.

 

I have observed below error on Thingworx Application Logs. Please find the attached "tomcat9-stderr" file.

When I see system logs in Event Viewer, I got this message "The Apache Tomcat 9.0 Tomcat9 service entered the stopped state at "2021-03-18 5:44:36PM". Before that observed "The IaasVmProvider service entered the stopped state at 5:40:21PM" in Event Viewer log.

 

Below are "omcat9-stderr" logs..
