when I use a servlet too many times- error

[Munteanu Gabriel]

I have a servlet that generates images dynamically.
Examples of requests:
imgChanger?text=Hello
imgChanger?text=Beautiful
etc....
I play with it about 10-20 times and after that, in IE, instead of
getting the image I am getting an img square[no image]
and tomcat says:
