Warning: Writelock due to read

We were using analyses and back-filling which involves reading from a pi-point at the same time new real time data are written to the same pi-point. The analysis is writing data to a completely different pi-point.

During this operation we had thousands of log entries as mentioned in this KB

That is all well and fine, but I fail to understand why a read way back in the past, locks the point for writing data to the same pi-point, even though there are a year between where we read with the analysis and where we write from the interface.

Is this working as expected.

We are using the latest version of PI.
