Gluster users - Dec 2008 - Rehashing because st_nlink less than dentry maps

Hello! I'm running GlusterFS few days, and all time tailing logs. So the
problem is:

2008-12-18 11:46:22 W [fuse-bridge.c:411:fuse_entry_cbk] glusterfs-fuse:
102688: (34) /impatt494a1bb451ace7.68312598 => 453 Rehashing because
st_nlink less than dentry maps

log enteries like above. I dont understand what this mean and what can
be cause of this. My Servers is on Hardened Gentoo (Grsec/PAX) (pax
protection disabled for flusterfs and glusterfsd) glusterfs-1.3.12. Two
servers is on AFR, and also has client setup for accessing glusterfs,
and also there are few client only setups. On clients I'm using
read-ahead and write-behind.
