I'm facing an issue using ats1.4.4 in resiliency mode where from time to time the RIC becomes STALE and we need to restart both instances to work again. Any way or clear this STALE mode without restarting? Have increased RESILIENCY_AR_BUFFER_SIZE parameter in the ats.params file as well as UPDATE_STALE_RECORD to TRUE, even though some fields from this RIC are STATIC_CONTRIB
General rule is that if one field is STALE, then the entire record is marked STALE. There are multiple reasons why a field could result in STALE: e.g. a calculation results in a division by zero, a function is using a blank when it expects a numerical value (e.g. after a closing run), one of the inputs to IF() is STALE etc.
If you can send a sample (or the entire ats.dico and ats.model files) I can understand better and perhaps recommend a solution.
