It sounds like the xattr disappeared for a "non rmxattrr" reason (the xattr is obsolete and was removed by a client application of the FS that supports xattr, but without notification to ganesha). So the client keeps a stale handle on the xattr fake file and tries using it.
This needs further investigation.
