Perforce Check out on agent, file name too long error, Windows

Hi,

I am trying to checkout on the agent. The source code does some computation using the svn information provided by Perforce. I am able to do a server side checkout.
But when i do agent side check out i get the following error after some time. Does any one know what is the reason?
