Re: [Condor-users] production ccb pool not communicating

I forgot to mention that we're using this version:

[samgrid@samgfwd06 ~]$ condor_version
$CondorVersion: 7.3.1 May 19 2009 BuildID: 154007 $
$CondorPlatform: I386-LINUX_RHEL3 $
This system was setup before 7.4 came out and we wanted to use CCB. Should I do a quick upgrade to the released 7.4.X??? Maybe there were bugs fixed relating to this? 

Thanks,

joe

Hello,
I've got a production condor pool that has been running for a while but is now getting communication errors with multiple remote sites. CCB is used to talk to the remote sites. The local machine is 131.225.216.64 and the schedd log seems to be saying that the local schedd can't connect to the local CCB servers running on ports 9877, 9878, and 9879.
This pool was in use and I'm not aware of any config changes made. I have restarted the pool and removed all the remote glideins since jobs weren't runnng anyway. Nothing helped.
The remote machines do seem to be properly reporting back to the Collector via CCB and it's the local daemons that don't seem to be able to communicate. 

Any help appreciated.
