Glidein sent unintentionally to multiple schedds on the Factory (Glideins sent to the wrong entry)
If the named schedd in the job.descript file is just "fermifactory01.fnal.gov" (no @ sign in front of it - the default system schedd)
Then glideins can and do get submitted to all schedd's on the machine.
When glideins are submitted to all schedd's on the machine then you can have the combination of more than one batch universe destination from the same user, which is what caused Dirk's problem of edison and cori glideins getting blended last week.
This was reported by Steve Timm and he had to rename the schedd as workaround to solve this problem.
