Re: WebApp Caching Broken

I’m guessing that the OP’s configuration or user permissions are not allowing war unpacking to update the webapps directory to the new version of the webapps. This has happened to me on some of my installations in the past when an admin starts as root vs. a special user like tomcat. This is

WebApp Caching Broken

We are having a serious problem with Tomcat (8.5). Twice it has decided to PERMANENTLY cache one of our webapps. We are unable to update that webapp. We've tried everything imaginable, short of uninstalling Tomcat, which is the next step. Where is this cache and how do we turn it off? Why

Infinite loop in Poller run - Tomcat 8.5.16 with APR native 1.2.10

Hi Team, We are observing the high CPU utilization often in our sandbox and production environment. We are using Tomcat 8.5.16 with APR native 1.2.10. It looks, the Poller thread is going in infinite loop while adding sockets which are waiting to the poller. java/org/apache/tomcat/util/
