Not suprising that lock_gulmd is working hard when gfs is under heavy
use.  Its it busy processing all those lock requests.  What would be
more useful from gulm for this than the logging messages, is to query
the locktable every so often for its stats.
`gulm_tool getstats <master>:lt000`
The 'locks = ###' line is how many lock structures are current held.
gulm is very greedy about memory, and you are running the lock servers
on the same nodes you're mounting from.


also, just to see if I read the first post right, you have
samba->nfs->gfs?
