Thanks Chris for an insight.
When you say "the number of open sockets and the number of
Tomcatrequest-processing threads will be the same". Does that mean all sockets
states whether its in Closed_wait,listening, stop etc... will consume a thread
individually.If yes then does that imply if i coun

Also, what Tomcat version? I'm guessing 6.0.x or 7.0.x. Can you give

If I write a servlet such as the above, is there ever only once instance of it
running?
Don't confuse objects with threads. There is one instance of a particular
servlet, but many threads may be executing in it concurrently, with each thread
processing a separate request.

The servlet I have in mind for modification is the one responsible for

results. If one or more of the wikis is unavailable, I want to display an

Note that everything you are using is very out of date. Tomcat just
released 6.0.18, mod_jk is at version 1.2.26 (and JK2 is dead, dead,

There are some thread-specific parameters you can play with, in

There's no limit within the JVM itself on the number of threads,

Actually another question is what is it in your application that NEEDS

Normally the creation of a thread is considered an expensive operation

place. Hence

Hmm,
I would suggest you stop having continuos connections. 30 seconds is a
lot of time, maybe you should re-establish connections on request. I
know re-establishing costs 3 additional tcp packets, but it negligible
since you have small packets sent seldomly.

You may want to try turning off keepalives in your tomcat. (I assume
