Jason Harvey commented on CASSANDRA-2170:
-----------------------------------------
Re-opening per request of driftx.
So, still seeing this problem ever since our upgrade from 0.6.7.
It is 100% consistent on 0.7.1, 0.7.2, 0.7.3, 0.7.4, 0.8.0, 0.8.1. I've tried
Sun JRE and OpenJDK. Tried with JNA and without. Tried Ubuntu
08.04/10.04/10.10/11.04, as well as RHEL5.1. It *only* happens on coordinator
nodes.
For the 0.8 ring, I created a brand new ring and added data from our app one CF
at a time. As soon as I added a busy CF, the problem popped up again. The load
on the boxes in the new ring is under 1 all the time, except for when the load
spike occurs.
