I tested all of the features of my application in Tomcat 8.5.37, so I don't prefer 8.5.42 for now. Sincerely, Nazmus

As the application is hosted in aws environment, there is a load balancer from aws. And I am using Apache (with ajp proxy) in front of Tomcat. Nazmus

Tomcat not responding (in browser) after undeploying docs and examples application.
Greetings. For security reasons, I wanted to remove docs and examples application. So, at first, I deleted both of their directories from the webapps directory. However, the remaining applications (including manager app) were not responding in browser (blank pages were being served), although the tomcat service was running in the server. The logs were not showing anything. Then I put back docs and examples directories in webapps directory, and things were back again. Then, I tried to undeploy them using tomcat manager. The undeployment works, but again I got blank screens for remaining applications. I even tried restricting access to these two apps (docs and examples) using valve and filters. And unfortunately, again the same issue: I get blank screens. Finally, I started with a clean installation. However, I get same result after undeploying docs and examples. Permission is not an issue, all contents belong to the tomcat user. I am using Tomcat 8.5.37. Operating System: Amazon Linux 4.14.88 Java version: 1.8.0_191-b12 Please advise. Thank you.
