After some months without errors, I’m repeatedly getting the following error

The Historical Tag Provider is based on SQL Server 2014, no partitioning, no pruning.  
Any idea?

Thanks in advance, regards

If the buffer is full then your disk cache may be full as well. I would start by looking at the Status\>Database Connections page of the gateway. This should give you a better idea of what is going on.
