This is an indication that your webapp is not managing its threads properly.

This is sometimes caused by incorrect timestamps on the bits of the webapp that Tomcat monitors,
or an incorrect clock setting on the system Tomcat is running on.  The mismatch makes it appear
that the webapp is being updated continuously.

If you want anything more than speculation, you'll need to provide real information: Tomcat
version, JRE version, platform, server.xml (with comments removed), context.xml for the webapp,
etc.
