Hello All,

My application works fine when I test it with my browser. But if I run load
test on it (25 parallel users) I start getting this exception periodically.

However in the stack trace I cannot see any of my code. Why is the struts
code generating this exception? That too only under minor loaded conditions?

I am using struts 1.1 on BEA weblogic 8.1

Thanks for your help in advance.

Here is the stack trace :
