Subject Re: Debugging help for SessionExpiredException
Date Tue, 15 Jun 2010 17:33:41 GMT
More on this...

I ran last night with verbose GC on our client. I analyzed the GC log in gchisto and 99% of
the GCs are 1 or 2 ms. The longest gc is 30 ms. On the Zookeeper server side, the longest
gc is 130 ms. So, I submit, GC is not the problem. NOTE we're running on Amazon EC2.
