Tomcat Class unloading/classnotfound problem

Recently in our web application deployed in tomcat, some weird problem is raising very frequently.
Some of the servlet or class in that web app are getting unloaded. So when the request comes it is sending 404 status or class-not-found exception.
So what we do is reload the context/application from the tomcat manager and then it will work fine.

Searched lot but cant able to find solution to this unloading or classnotfound problem.
Can anyone suggest me why this is happening.

sorry to say wrongly, its not classnotfound exception . It is NoClassDefFoundError
