I am sorry. I thought load balancer is something related to tomcat and
asked so many questions. Really sorry for that.

Yes I can check those configurations. In the meanwhile I have another
question. Please take a look at the log below.

Hello Kumar,
can't you just ask your Ops guys to get your the load balancer config?
That would be much easier as guessing.
Usually you can configure how many samples the load balancer must try to
get and what is the timeout. For example if the setting is 3 with timeout
of 15 seconds, 3 requests w
what I mean is if I am supposed to get a response for that Update.jsp file
and I didn't get it for a while. Will the load balancer will check for it
connectivity? Is there any timeout set for load balancer to get response.
Thanks,
Kumar.

Yes its the load balancer. and recently I found in the log that there was a
memory leak exception while the tomcat server was restarted.The session
increase problem started from this particular date . Could this be a cause
for the tomcat to hang up and DOS occurred?

I 'm using tomcat version 6 and 7. One day there was a sudden increase in
number of sessions in both tomcats. And all the sessions had no username,
same lastaccessed time, same created time and the inactive time was
00:00:00. It is not happening always but it happens some times on some day.
