Hi Folks,
I have a web application that, after a period of inactivity (1-2hours), will stall for 3 – 35 seconds upon the first new session. All subsequent sessions will not experience this delay unless another period of inactivity occurs. I’ve found that the delay occurs when loading jars that live in the WEB-INF/lib folder. The issue doesn’t occur when the server is first started. Only after a period of 1-2 hours approx. will the next session experience the delay when loading a jar. This leads me to believe that when the server is started ‘knowledge’ of the jars might be cached, however, after a period of inactivity this cache may expire. The result of this is that the next session after this period causes the lib folder to be searched again which seems to take the 5-35 seconds. My question: Is this theory above correct, and if so, is there a way to configure Tomcat such that this cache doesn’t expire so that it doesn’t need to be re-populated when a new session begins? Tomcat Version 9.0.10 Any help appreciated, Thanks, Niall
