If reached memstore global up-limit, you'll find "Blocking updates on" in your files(see MemStoreFlusher.reclaimMemStoreMemory); If it's caused by too many log files, you'll find "Too many hlogs: logs="(see HLog.cleanOldLogs) Hope it's helpful for you:)

The current memstore reserved (IIRC) would be 0.35 of total heap right ? The RS total heap is 10231MB, used is at 5000MB. Total number of regions is 217 and there are approx 150 regions with 2 families, ~60 with 1 family and remaining with 3 families. How to check if the flushes are due to too many WAL files ? Does it get logged ?
