Please give me some information/hints regarding this error:
[PI SDK][<tag name>] Failed to retrieve events from server. [-11002] Record Header Data Mismatch.
The error occurs when querying <tag name> on data that is older than 70 hours, that is when we extract data 40h ago, everything works fine. That database that we extract data from had "some issues" some days ago, and I wonder if the "Record Header Data Mismatch" indicates that the data (older than 70h) is "damaged".
Could this message indicate that the data is lost, or is this something that can be fixed?
