Confluence won't start after move

Doug Wolfgram

I moved JIRA and Confluence to a new server. I moved the databases (mysql), the app directories and after installing, also moved the installation directories. JIRA starts and runs fine. Confluence starts with no errors. I can see the process in ps -ax, but when I go to the page, I get a white screen.  

The only thing that comes to mind is that this new machine only has 1 core and 4 GB of RAM. Is that adequate to run both JIRA and Confluence? Are there any other logs I can check to see why I am getting a white screen?  

After I try to access the page, I get several instances of this in catalina.out

05-Mar-2016 19:29:13.668 WARNING [localhost-startStop-1] org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesThreads The web application [ROOT] appears to have started a thread named [com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread-#2] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread: java.lang.Object.wait(Native Method) com.mchange.v2.async.ThreadPoolAsynchronousRunner$PoolThread.run(ThreadPoolAsynchronousRunner.java:534)

 Does this mean I am out of memory>?

System requirements are highly dependant on your configuration and usage. We cannot ever truly say whether 4 GB of memory and 1 CPU core are sufficient because surely you could make it work to some extent. 1 CPU is also extremely unclear. Is this a Pentium 2 single core? Probably not, you likely have a VM. How is this VM configured and hosted? You understand what I mean, there's no details in your post to aid with a system recommendation.

Furthermore since you moved an installation, that means you took the JVM settings from your previous install. So the question I need to ask you is, how much memory have been set to these applications within the setenv file?

Finally, you may find more relevant information in the application logs instead of the catalina logs. I wouldn't worry about the error you posted above.
