[gridengine users] qhost reports removed compute nodes

'qhost' on one of of our clusters (running Rocks 5.4.2
with SGE 6.2u5) had been, for a while, reporting nodes
that had long been removed.

   1. 'rocks list host' did not report them
   2. 'ganglia' web interface did not report them

The following attempts did not do the trick:

   1. 'insert-ethers --remove compute-X-Y'
      (this reported that 'compute-X-Y' was removed)
      followed by 'rocks sync config'

   2. Restarting 'gmetad' and 'gmond'

I did steps below to get rid of them from being reported:

   1. qmon
   2. Task --> Host Configuration
   3. 'Delete' the removed nodes from under 'Administration
      Host' tab
   4. 'Delete' the removed nodes from under 'Execution Host'
      tab --> Done
   5. File --> Exit

'qhost' no longer reports the removed nodes.


PS: If this is not recommended approach, please do let me know.
