Lustre discuss - Jan 2010 - ll_inode_revalidate_fini()) failure -108 inode

Hello,
Using 1.8.1.1 server/patched client, with one OST for now, 
remote directory mounted with "flock" option.

I the following appears in kernel log: 

LustreError: 12864:0:(mdc_locks.c:618:mdc_enqueue()) ldlm_cli_enqueue: -108
LustreError: 12864:0:(mdc_locks.c:618:mdc_enqueue()) Skipped 2103 previous

LustreError: 12881:0:(file.c:3143:ll_inode_revalidate_fini()) failure -108 inode
1024203
LustreError: 12881:0:(file.c:3143:ll_inode_revalidate_fini()) Skipped 2103
previous similar messages

With the same inode number each time. Actually, this appears only
on one lustre client (for now there are two, both use flock).

What this message says ? Shall I lfsck the filesystem ? 
Regards,
DT
