[Gluster-users] "UNLINK [...] returned NULL inode" message in client log

Hello all,

Lately i've been seeing the following messages over and over again in my 
client logs :

2008-11-17 01:52:51 E [fuse-bridge.c:1163:fuse_unlink] glusterfs-fuse: 
143141519: UNLINK /directory/sub-directory/file.ext (fuse_loc_fill() 
returned NULL inode)

This type of message has occured over 3000 (not a typo) times since 14 
November alone, so it's getting hard to ignore.  It seems to occur 
"randomly", which is to say that there appears to be no pattern to the 
type of file or the timing of the message.

I don't know what it means, exactly, so i'm not even sure if it's 
causing problems ; however, there have been some complaints about files 
which are "empty" on the client, so perhaps the two are related.

Any pointers on what this message means, what sort of effects might be 
exhibited by the given condition, and how i might go about fixing it are 
more than welcome. :)
