I would start by reading the logs in $CATALINA_HOME/logs to see what is causing Tomcat to crash.

There are two possibilities you need to consider:
1. Your application simply needs more memory to operate with the given load.
2. Your application is not properly managing memory resulting in so-called memory leaks which eventually crash the system.

If this was my problem I would start by monitoring Tomcat with the manager application, paying particular attention to the memory and Thread statistics. Does this application use connections to databases?

Thanks for your reply william,

Actually i am not using database,Datas are stored in XML files.
In server, we had 1 GB RAM and we configured Apache Tomcat Properties as -DCatalina.opt -xms 768m - xmx 1024m

but still the problem is occuring.

That's not how I usually set the heap space.
If you go to the ServerStatus section in the Tomcat manager app (http://localhost:8080/manager/html) it will show you how much memory has been allocated to the JVM.
 
I agree. Here's the link: http://aspose.com/file-tools
