I have developed a website in Java Spring. It has very good foot fall around 5000/-day. I have deployed it on Java Apache Tomcat server. On daily basis it stops 2-3 times. I am getting memory leak issue but I am unable to identify where this leak issue or why this is happening.
I am getting following log from Apache:
SEVERE: The web application [ ] created a ThreadLocal with key of type [org.springframework.core.NamedThreadLocal] (value [Locale context]) and a value of type [org.springframework.web.servlet.DispatcherServlet$1] (value [en_US]) but failed to remove it when the web application was stopped. Threads are going to be renewed over time to try and avoid a probable memory leak.
