Actions

JK to investigate why ralreplicas fails and submit a "bug" report

RA/BD: Run GFAL unit tests against CASTOR. Get them here: https://gitlab.cern.ch/dmc/gfal2/tree/develop/test/

GP/RA to write a Nagios test to check for large number of requests on the NewRequests DB table that remain for a long time - the check will run every xxx min (to be aggreed with Production) and issue an alarm if the number exceeds 1,000 for an extended period of time (15 min)
