Re: [HTCondor-users] Collector not reachable on localhost?

[Thomas Hartmann <thomas.hartmann@xxxxxxx>]

Hi all,

just to close this issue : scraping and respawning the collector 'fixed'
the problem and the daemons can communicate with each other again.
No idea what the actual problem was, maybe some networking problem
within OpenStack...?

Cheers,
