Hi Chris/All,

       Actually we are getting

Exception-Servlet execution threw an exception
Exception Cause-java.lang.NoClassDefFoundError:

We are running tomcat in centos.
Web app initially running fine, and in the high load time this error is
happeningo some of the class files randomly.
Is there any relation between max-open-files in linux
and NoClassDefFoundError in runtime.
