[Condor-users] Quill++ assistance

I have been trying to set up Quill for our pool so we can track HTC use. I have followed the Condor manual for configuration of both the configuration files as well as PostGres. Quill will work for several hours but then most of the machines are dropped from the pool according to Quill. For example, If I enable Quill everything seems to work for at least several hours. But usually by the next morning Quill is not tracking any of the machines and all machines are dropped from the pool (as seen via condor_status). The Condor daemons are still running on each machine however.

This seems to be related to the password/security based on the errors I am receiving below, but the database tables are populated, all the sql log files have information and everything looks ok.

I have a homogeneous pool with Windows OS working nodes and our central manager is running on Windows 2008 server. Postgres is also running on this same server. Our bandwidth is 1Gbs and our pool is small (50 machines right now).

Can anyone help me understand what I may be doing wrong or what the problem might be related to.

Thank you for the help,

I am getting an error that the condor_quill.exe(exit 4) has exited via email to the administrator:
