interface rejected all PI Points

Hey All,


Recently ran into an issue where the PI OPC interface will occasionally stop working, often following all the tags giving both a tag value, immediately followed by a "bad" tag value at the same time stamp.

The associated error is "Interface rejected all PI points", with no additional information as to why, as seen below


Restarting the OPC DA server service, followed by the PI-OPC interface fixes the problem, but this has been happening about once a month, and wanted to know what might be causing this to happen that often.


If anyone has experienced any similar situations, please reach out to me.
