Subject Re: Upgrade Tomcat procedure [to avoid latency/UI bug]
Date Thu, 21 May 2015 15:32:43 GMT
Hi again Andrija,

I saw on that issue that upgrading to tomcat 6.0.43 doesn't seem to fix the
issue for you, perhaps you can try another approach :)
I've seen a similar problem where there is no response from the management
server (taking from a few seconds to quite a few minutes, depending on the
environment). The issue i spotted is a well know problem with random number
generation with java in linux, and affects some environments more than
others, depending on the ammount on enthropy generated in the system. VMs
suffer from this the most...

Can you add this to the JAVA_OPTS to the
/etc/cloudstack/management/tomcat6.conf and retest?

-Djava.security.egd=file:/dev/./urandom
