Re: [xwiki-users] OutOfMemoryError: GC overhead limit exceeded on a new installation

I tried removing the garbage collection parameters but still got the out of memory errors so I tried removing all the Java parameters and got the same behavior. Vincent, I started with "-Xmx1024m" but increased it to 2048m after getting the out of memory errors and reading the page you referenced (http://platform.xwiki.org/xwiki/bin/view/AdminGuide/Performances#HMemory). I also used the parameters and values that page referenced as what is used on the xwiki.org site. The other odd thing is that every time I restart Jetty, the Distribution Wizard starts. This is my first experience with the Distribution Wizard, but I'm guessing that isn't the expected behavior. It even starts up when I restart Jetty before running into the out of memory errors.

I probably also should have mentioned that the VM I'm trying to run xwiki on is configured with 8GB of memory and 4 vCPUs. Any other suggestions for how to get a stable installation running?

Thanks, Jared This is the most recent error I got during testing this morning: 2016-07-19 07:56:20,847 [http://nhhqwiki01:8080/xwiki/bin/view/Infrastructure/Policies%2C+Process%2C…] ERROR
