Hi 

We have more than 200 hosts that has Jailer/Jail environment and when
developers try to access the tools from /volume path below error pops up ,
there is no particular pattern on when this error occurs or its not always logs
when the volumes are accessible , we have similar 7.1-RELEASE-8 FreeBSD
standalone servers and similar issues are noticable when ever we have some
genuine problems with NFS source or Network , we could not dig more on at what
particular circumstances this error comes , or is this a known issue in similar
kind of environment or any more tuning needs to be done to eliminate this
problem , vi or access to the volumes goes on toss for couple of seconds when
this error occurs , this particular error pops up on all the 200+ hosts that is
havin similar configuration
