Re: Excessive memory usage with 1.3.12

Thomas,
We want to reproduce the leak in our setup to fix it. What is your
setup on the client side? How many servers do you have? What are the
applications you run on the mount point? Do you observe leak only when
"certain" operations are done? (I am just looking for more clues)

Thanks
Krishna
