I upped it to 256K.  What I am trying to wrap my head around is how it was 
working somewhat for so long at 24K, but it got to near 65K before I 
rebooted it with the higher setting.   Or did I reboot too early?  Is 
there any cleanup that isn't triggered intil it reaches max nmbclusters? 
I am trying to see if anything on our network has changed to cause this to 
become cronic.
