    Linux UI Hangs with App Server Running

    Mark Howard Newbie


      I'm getting an odd error when running jboss app server on linux once the initialisation is finished.
      Various GUI applications become very sluggish or freeze, for example firefox takes several seconds to open a menu. The CPU and disk usage are both minimal (as reported by top and atop) and there is lots of free memory. As far as I can tell, the system is otherwise working correctly. The issue is definitely related to jboss app server because it starts when jboss starts and stops as soon as I stop the app server.
      As a result of this, jboss is effectively unusable on this machine.

      I don't get this problem if I run the minimal configuration of jboss, but do get the problem with the default, standard, all and web configurations.
      I'm running ubuntu 9.10 with kernel 2.6.31-9-generic. I get the same problem with jboss 5.0.1 and 5.1.0

      Any ideas what could be wrong or what else to try to debug this?
      I've already tried changing all the port definitions I could find, in case there was a conflict, but this didn't have any effect.

      If it helps, the output from starting up with the web configuration is below:

          Looks like you are using the Sun JVM that Ubuntu provides. Personally, I would download the JVM from Sun's web site and install it and use it.

          Have you looked on Sun's web site to see if any issues have been posted regarding the JVM is this newer version of the kernel? Often, when a new OS level comes out, there will be patches in the JVM to "fix" problems. That is one of the things you have to put up with when using beta OSes.
