We have a critical system that is highly dependent on Appfabric Caching. The setup we use is three nodes which serves around 2000 simultaneous connections and 150-200 requests/second.
Configurations are the default ones. We receives maybe 5-10 "ErrorCode:SubStatus" each day which is unacceptable.
I have added some performance counters but I can't see anything weird except that we sometimes see values on "Total Failure Exceptions / sec" and "Total Failure Exceptions" is increasing but one 2-3 times a day.
I would like to see what these errors comes from but I can't find them in any logs in the Event Viewer (enabled them all according to documentation). Does anyone know if these errorc could be logged somewhere and/or if it possible to seem them in any other way?
