Why can't the native library 'libFusionReactor.so' be loaded?
Description
If you run ColdFusion MX 7 Multiserver on Linux/Solaris and have used InstanceManager to install a second instance of FusionReactor on another ColdFusion MX server instance named 'cfusion2'. The InstanceManager told you to restart the server so you've restarted my 'cfusion2' instance with the following commands:
sudo -u nobody /opt/jrun4/bin/jrun stop 'cfusion2'
sudo -u nobody /opt/jrun4/bin/jrun start 'cfusion2' &
When the server is restarting you see the following in the server log file:

The native library has been already loaded in another classloader.
Restart the complete server after having added a FusionReactor instance:
sudo -u nobody /opt/jrun4/bin/jrun stop
sudo -u nobody /opt/jrun4/bin/jrun stop
Note: We might revise the destination of the native library for JRun based servers in the near future.
