1% local replication reserver warning

Hello,

Does anyone know why we are getting these warnings in the monitoring from equallogic?

Level Warning
Time 9/2/2014 9:36:20 AM
Member eq-member1-sm1
Subsystem VolExec
Event ID 43.3.5
Message Volume VMware-SM-ChamiloWeb has used 1 percent of its local replication reserve. If the in-use space exceeds the local replication reserve (set to 5 percent of the volume reserve), the group will cancel any in-progress replication for the volume.

The volume is 150GB and 7.5GB local replication space is more then enough to replicate to the partner because the replication schedule is set to every 5 minutes.

I can't choose to replicate faster and I know that the local replication reserve never will exceed the 7.5GB

Thanks
Stijn
