Thanks for posting the log. I highlighted a few interesting messages, which show what is going on:

As you can see, all those events happen in the [Refresh Packages] thread. This means they are a result of the ongoing installation. Some of the bundles your are installing trigger a restart of core Gyrex bundles. This causes the server to restart.

You should see more when you enable debug logging or tracing for Equinox bundle activation.

There is one interesting exception in the log, though:
..
11:59:11.053 [app thread - org.eclipse.gyrex.http.jetty.applications.engine.0] ERROR o.e.g.h.j.i.JettyEngineApplication - Unable to start Jetty. Please check the log files. System will be shutdown.

        at java.lang.Thread.run(Thread.java:722) [na:1.7.0]

This is in the middle of shutdown and shouldn’t be logged there. It could be a problem in Gyrex. Can you try with the latest version?
