Out of memory

[Arathi Raj]

Hi,

We have application running on tomcat server. That application mainly used to run reports in form of pdf and excel. it talks to 3 differnt databases to get the data and outputs to pdf and excel. Most of the time application runs fine , but in few cases it throws out of memory. I increased the heap size to 1 GB but still the same problem.

The other thing apart from above application we are running 3 other different applications on same tomcat server.

Of all we have two versions of tomcat installed on same server and in each versions of tomcat we have 3 to 4 applications running.

Now my concern is it because of our setup does it leads to out of memory problem or what others things might cause the problem.

Let me know how we can improve the performance.

Thanks
