We have few set of advice tags which are updating frequently. We have also enabled the compression and exception max for these tags so that it should have value at every 8 hours if the value is not changing at source side. But tags are getting frozen if the values are not changing. We have to scan off and than scan on to resolve this.
For a tag, I noticed that at source it is having same values from past 7 days but in PI, for 3 days comp max worked properly but tag got stuck after that.
Kindly suggest what could be the real issue here.
