Hello,

I am looking to reproduce this bug, in order to write a regression test
for it. I have the correct lustre modified kernel for Red Hat EL3u7
(2.4.21-40) lustre 1.4.6.4 , but I am unsure about the circumstances
that lead to the number of open files "growing."

Is this a reference to processes opening files, then closing them, but
the file descriptors remaining in /proc/<pid>/fd . If not, where should
I look to see reference to these open files?

Any help in reproducing this would be gratefully received.
