My installation is on Centos 5.8, NetXMS 1.2.9 compiled from source and running a jetty 7.6.9 instance from a compiled rpm.

Using the web console and connecting through chrome; logging in, actioning alarms and various other activities are fine. But when I attempt to create a new object tool or edit a tool, a window is presented to "run in background". Clicking run in background sits for some time and will eventually timeout.

Reviewing the jetty logs I see the following

2013-11-06 12:33:20.514:INFO:oejs.AbstractConnector:Started SelectChannelConnector@0.0.0.0:9090

Any thoughts or suggestions on what I should look at and review to help resolve the issue. Plus once this event occurs, I lose connectivity to the server and need to restart my web session.

Lastly, is there a good reference to configure a tool (object tool) which can be called from a pop-up menu in the alarm browser?
