How have you proved this?
Take a thread dump (you're on Java 1.6, so you can use jstack). What are the
threads doing?

OK. You've done more research than most, then - we get a lot of people blaming
Tomcat as the first thing they do, so we tend to have some

The application doesn't have problems as I tested it with Visual VM (profiler
for java 6) on Windows. But I need the application on Linux. I'll try to
take the thread dump and see. Anyways, can there be problem with Tomcat? I

So, I'll take the dump and analyze and revert back.
One more confirmation. Is the executor configured by me for Tomcat
appropriate? Or should I make any more changes?

Anand,
As others will surely tell you, there is something amiss in your
application that spawns threads. However, the maximum number of
threads Tomcat will handle is somewhere about 2400. So, if you are
getting an error at 1000 threads, look somewhere else.

Ya. I think I will have to re-analyze the code.
I have one doubt. Should the code I write be thread safe?
Following is the excerpt from the thread dump of different threads at
different states:

I'm curious: where did you conjure up that number? The actual limit will vary

Usually. If it's within a servlet, then it *must* be thread safe, since a
servlet instance may handle multiple requests simultaneously
1000 threads come up by themselves. I have configured Tomcat to spawn only 70
threads.
Also, I'll look for synchronization issues in the code.

Something must be wrong. Your executor configuration:

Should I make any modifications anywhere?

why not start by creating a backup copy of your server.xml, and then
removing all of the commented out config.
it'll be easier to see what's going on that way...

I hope you also realize the file name must be server.xml, not Server.xml (case
matters).
