Hi Chris, We have not set the autoreload setting at all. I believe by default its set to false. Please correct me if that’s not the case. Also manager is disabled in our environment.
I used the watch command along with lsof highlighted below . Watch "lsof <directorypath>/WEB-INF/lib/*.jar" Jalaj -----Original Message----- From: Christopher Schultz <ch...@christopherschultz.net> Sent: Wednesday, January 20, 2021 4:41 PM To: users@tomcat.apache.org Subject: Re: Reg: Jars under web-inf lib being accessed by tomcat even when the application is not running.

Tomcat runs a background processing thread that allows various components (e.g. engine, context, etc.) to perform background tasks. One such task is checking for file-updates that may trigger a reload. These checks are skipped when auto-reload is disabled. lsof usually shows a snapshot of file handles. How are you determining that Tomcat is /repeatedly/ opening files and not just keeping them open?
