Jfree Chart randomly displaying a cross instead of image

[deepaSingh]

Hi,

A very trivial issue I am facing wherein the Jfree charts appear properly when I run the application on my local server, but when I deploy the war on dev server, the charts do not appear sometimes, instaed a cross is displayed. This happens when I display multiple charts on the same page.
Can anyone tell me the issue as the logs also do not show any kind of error so its hard to understand the reason.
