I would like to offer a formal apology to anyone who has followed my
memory tuning advice that includes the "-XX:NewRatio=1" option. I have
lately learned that this setting is causing me a problem I didn't even
know about - extremely long pauses during young generation (ParNew) GC,
leading to occasional super-long queries and load balancer health check
failures. I was warned this might happen, so some of you get to say "I
told you so!"
I am still working on my config, so I don't think it would be
appropriate to share it at this time. After I've done a lot more
testing and can reach some reasonable conclusions, I'll share the final
results.
Thanks,
Shawn
