Hi Lei,

I think that we may have found your problem.  There is a subtle bug in
pvfs_open() in 1.6.2 that you might be running into in this case.

Could you try applying the attached patch to 1.6.2 and see if it fixes
the problem for you?

This patch has already been applied to cvs, but today might not be
the best time to check that code out (we are in the middle of some other
unrelated clean ups at the moment).

thanks!
-Phil
