Does this period coincide with garbage collection?  (Although 4 - 7
seconds is rather long for a GC.)  Have you tried using a profiler to
see where the threads are spending their time?

> how can I ask Tomcat to kill these non working threads ?

What do you have maxSpareThreads for each of your connectors set to?
Look here for the HTTP connector doc:
http://tomcat.apache.org/tomcat-5.5-doc/config/http.html
or here for AJP:
http://tomcat.apache.org/tomcat-5.5-doc/config/ajp.html
