Futex_wait_bitset_private Etimedout (connection Timed Out)


Re: Java Performance on VMware ESX tcutts Jul 7, 2009 8:10 AM (in response to tcutts) Another tomcat application has just been reported to me with the same issues. How should I respond to absurd observations from customers during software product demos? Your server's configuration (being either v0.8 or v0.9.1) may still specify heartbeat '0'. Hacker used picture upload to get PHP code into my site how to remove this battery tray bolt and what is it?

For me the issue was that, after exactly 10 mins of normal operation (under jruby), my process would start using 100% CPU. How do I find more information on those fds? The solution: configure :heartbeat on server and client. Strace to View Deadlocks Let's use strace command to view deadlocks.

Alternatively, you could try running the application on a different OS to see whether the behaviour changes..If the workarounds or a different OS do not help, the following information might help I will try @thieso2's container later today. So I guess the leap second could be the cause after all. I don't know whether these are valid for ESX 3.5, but since your problem seems to be related to timekeeping, I would suggest giving them a try.We have already followed those.Alternatively,

Member michaelklishin commented Mar 13, 2013 Well, Bunny 0.9 uses a network activity thread that basically does while true. The remote server is rabbitmq 3.0.1 on centos6 in a xen vm.

After the heartbeat timeout has run out, bunny throws in the towel and starts to consume all those delicious CPU cycles while wallowing in it's own to speak.
