On a Pega CDH 8.6 platform running on kubernetes, we noticed huge number of records were written to IH for a 2 hour duration this falls in a window where we had cluster patching on environment side. All happened during this event was rolling restarts of pods. Reviewing some data at low level shows these are duplicate IH entries from old/existing interactions.
what could have caused something abruptly to resave this IH into DB? Appreciate if you have any inputs, thank you!!
