[FRS-403] Possible Performance Issue on FusionReactor 6.2.0 – 6.2.4


This technote is going to provide you with more information and a workaround for a potential performance issue that has been identified in FusionReactor 6.2.0 – 6.2.4.

More Details about the Issue

In FusionReactor 6.2.0, a new plugin was introduced to track the overall application and database performance called the HitCount plugin. In a few cases (typically when you have a very large number of pages) the plugin may consume too much memory over time and as a result, longer garbage collection times may occur and eventually the memory could become exhausted, similar to a memory leak.


A temporary workaround is to disable the HitCount plugin.

In order to do that, please follow the steps described below.

  1. Stop your Application Server.
  2. Locate the JVM arguments file and backup that file.
  3. Open the JVM arguments file with a text editor of your preference and add the following argument: -Dfr.osgi.inhibit.fr-hitcount-plugin. By adding that argument, the HitCount plugin will be disabled.
  4. Save the changes.
  5. Start the Application server.

If for any reason you experience any issues please restore the backup of the JVM file and restart the Application server.

Please note that the development team is working for a fix which will be available soon. If you have further questions or issues with FusionReactor, please feel free to contact the Support Team on the following email: support@fusion-reactor.com.
