I have just migrated from 6.1 to 6.5 and now I am seeing the errors below several times on the log files.
2017-07-13 19:53:35 WARNING [DatabaseCacheStoreManager] unable to obtain SmartAnalyticsEngineStatistics Suppressing this warning for another 60000 ms.
2017-07-13 19:53:47 WARNING [LazyDatabaseCacheStore] Could not get store for analysis cache key AnalysisCacheKey
Furthermore I can see that although I am connected to the PWH information is not being stored as I can only see metrics for the past 30 minutes.
Does anyone has any idea of what could be going on? I have already opened a ticket to the support, but would like to hear if anyone has ever experienced such errors.
