[torqueusers] pbs_sched: badconn, "unauthorized host" on multihoned system

[Steve Crusan]

I believe you need to check the /var/spool/pbs/server_name file for the
pbs_moms on your nodes.

Also, check that the pbs_server configurations files (torque.cfg) use the
correct hostname, as well as the pbs_mom files.

Recently, we upgraded to a new version of torque, and it seemed some of the
configuration files were changed. We were having similar problems.

Good luck!
