------------------------


When renaming hosts (e.g. by using an host_aliases file) and restarting the
qmaster daemon the spooled objects which are read at startup are re-resolved.
The re-resolving is not consequent enough. The queue instances still have the
old name. The @allhosts group still contains the old host name. Other problems
might be the used path to the spool directory of the installed execution deamon
on that renamed host.

WORKAROUND:
Remove the host from gridengine qmaster before renameing it.
Then add the host from scratch.
