[GE users] More startup oddness

I'm getting an unusual error on starting the grid engine service
on the qmaster:

 root at linux6:~# /etc/init.d/sgemaster start

 sge_qmaster didn't start!
 This is not a qmaster host!
 Please, check your act_qmaster file!

.. so to get a bit more information, 

 root at linux6:/home/pipelines/SunGE#  export SGE_ND=1
 root at linux6:/home/pipelines/SunGE# ./bin/lx24-amd64/sge_qmaster

 Reading in host group entries:
         Host group entries for group "@allhosts".
 Reading in usersets:
         Userset "defaultdepartment".
         Userset "deadlineusers".

         Queue "all.q".

 error: commlib error: local host name error (remote destination host name "linux6" is not equal to local resolved host name "localhost")
 error: can't create job sequence number file "jobseqnum": Permission denied - delaying until next job

.. it hangs at this point. The host is known as 'linux6', and this is
what's returned by the 'hostname' command. The act_qmaster file contains
simply 'linux6'.

Why is the startup resolving the hostname as 'localhost'?
First line of /etc/hosts is: localhost linux6

.. any suggestions?
