Urgent: Java memory problem

Posted by Rajesh on October 06, 2001 at 8:07 AM


We are developing a JSP Application with the following architecture.
1) OS - Windows NT 4.0
2) MS-SQL Server 7.0
3) JDK 1.3.1_01 (Standard Edition)
4) Apache Web Server 1.3.20
5) Tomcat 3.2.2
6) PoolMan 1.3.9
7) Sun's JDBC Driver

Our application has around 1500 JSP pages and 500 Beans. The number of users is around 250, concurrent hits to the server is around 50. The Hardware architecture is Pentium II 500 MHz with 393 MB Ram and 10 GB Hard disk.

The application is having performance degradation on constant usage for around 3-4 hours. The application is also having 'Java crash down' after a usage of 8-9 hours. The tomcat engine is shut down automatically. Is their any possible solution for performance improvement and avoiding Java crash for this application?

Thanks in advance.
