I have a problem about Memory Leak in Tomcat server.
When I undeploy and redeploy the error message war appeared as below:

The following web applications were stopped (reloaded, undeployed), but their classes from previous runs are still loaded in memory, thus causing a memory leak (use a profiler to confirm): /myWebApplication

How can I fix it and deploy as normally
If anyone known that , please help me .
Thank you very much !
