If two SqlSource configurations are set up and talk to different database servers, and then both configurations are run from the same SyncJob (ie: CoreJob.Sync s without -ois_id), the second SqlSource may be processed using the same SqlServer configuration as the first, which is likely to create errors for obvious reasons.

(A workaround is to run each OIS individually, ie CoreJob.Sync --ois_id 1 and then CoreJob.Sync --ois_id 2.)
