Hi Martin,
Thanks for sharing, on the surface there does not seem to be any issue in configuration causing the failures. I'm personally running KVM and Ubuntu hosts based env without issues, I'm on Ubuntu 14.04.4 (Linux bluebox 3.16.0-45-generic #60~14.04.1-Ubuntu) and java 1.7.0_79. Can you try upgrading your JRE7 to latest (openjdk-7-jre, 7u111-2.6.7-0ubuntu0.14.04.3) on all mgmt server and kvm hosts? If upgrading your JRE does not help, can you increase the logging verbosity for both the agent and management server (in /etc/cloudstack/{agent, management} there would be a log4j file, edit that and replace DEBUG/INFO with TRACE for class/keys com.cloud and org.apache.cloudstack) and re-share logs when the failures occur? I want to see what additional information we can get from logs when it tries to connect to host 10.100.12.10 on port: 8250. Regards. ________________________________ From: martin kolly <martin.ko...@senselan.ch> Sent: 25 August 2016 17:11:06 To: dev@cloudstack.apache.org Subject: Re: CS 4.9 NIO Selector wait time PR-1601 @Simon: We have one management server with local DB.
