At 7:13 this morning most if not all of my history tags created duplicate ID’s in the sqlth_te table. If I query these ID’s in the history partition table there is one row associated with it with quality 600. This is the same for all of the history tags I changed. It caused all of the trends to spike down to 0 because of the null value in this row. I checked the console and there was a message about some kind of loss of communication to the backup server at this time but not much else. Any ideas what could have caused this? I have to go through and manually delete these ID’s to get the trends to look normal. Thanks!
