Hello All,
I had posted this yesterday, but didn't receive any response so far. This
error is coming more and more frequently when we increase the load on
struts. Worst thing is that the stack trace shows that this error is not
originated from any of my source. It seems to be an error being thrown by
struts.
The error is coming only during load testing. It doesn't come during a
single user testing.
I am using struts 1.1 on BEA weblogic 8.1 on HP-UX 11i.
Can anyone who is an expert on struts internals have a look at this and tell
me what is going wrong?
Thanks for your help in advance.[Sorry for reposting this... But since using
struts was my idea, now I am being questioned... And I have no clue about
why this error comes]
Here is the stack trace :
