I am not sure if this is the right forum for my query. Please move it to the appropriate forum incase you feel so.
No problem. I have transferred you over to the applications forum.

You can use ps to monitor the tomcat processes, but this will not tell you if a process hangs "for a few seconds", as you say it does.

Have you made sure that tomcat really stops logging? Might it be that it simply had nothing to log for these few seconds?
