Gary, I have run a full write test with the SVN 0.6 Cassandra from yesterday which I'll call 0.6.3 beta. I am definitely not seeing the problem in 0.6.3 beta. I am seeing something different than in 0.6.2 that is probably totally unrelated. I can tell you more if you are interested and want details.
The headline is that when I run my 8 write clients (all on separate nodes) with 10 cassandra nodes and my clients are writing as fast as they can with consistency=ALL with 0.6.3 beta, I get timeouts within 2 minutes of starting my run. When I drop back to 0.6.2, I do not get the timeouts even after 30 minutes of running, all else the same. I have cpu usage and disk io stats on all my cassandra nodes during the 0.6.3 beta run if they would be helpful. I am going to go back to 0.6.2 until 0.6.3 is officially released. Just wanted to try it out and let you know if I saw the problem. Interestingly, since updating our JVM, I'm not seeing the tight-loop problem in 0.6.2 either. Thank you for your help! Julie
