We don't have many reprocessing jobs that were launched after LHCbDirac v7r1 based on Dirac v6r1 was put in production, but we observe very strange and annoying features...
From production 12955:

1. Job 28040682: TargetSE = SARA-RAW, Sites = LCG.NIKHEF.nl only and no other site. Job Done

2. Job 28040692: TargetSE = SARA-RAW, Sites = LCG.CERN.ch only and no other site. Job Done. This is really looking weird

3. Job 28040698: TargetSE = SARA-RAW, Sites = LCG.UKI-LT2-QMUL.uk only and no other site. Job Done

4. Job 28040694: TargetSE = CERN-RAW, Sites = DIRAC.CERNVMTest.ch only and no other site. Job will wait forever...

It looks as if a site is firmly selected by the optimisers amongst the many potential sites, which is not at all what we want. We want all sites close to the TargetSE to be eligible.
Could this be fixed, or explanations given on the behavior of Dirac?
