Comment 2 Ivana Varekova 2009-08-17 10:39:55 UTC 
Hello,
please could you attach here file
/proc/self/mountstats
from affected system?
Comment 3 Steve Dickson 2009-08-17 15:10:48 UTC 
There was nothing special about contents of /proc/self/mountstats
although I did have the NFS server (via service nfs start).

Please, do you have a test case for the problem you report?
