NNPFS panic

[Gregory Davis]

Hello, I found this error in my log recently, and don't know what it means:

Apr 18 09:59:54 uranus kernel: NNPFS Panic: nnpfs_message_installdata failed 
nnpfs_fh_to_dentry = 00/60, errno: -2

About 20 seconds before that, and the previous entry in my log, my credentials 
expired.  That error has never occured when they expire, and expire or not, I 
still get busy inode behavior when my kernel max's out cached physical 
memory.  Using 0.36-pre27.
