Check the logs from your Gateway (either through the web interface or by looking at the wrapper.log file). It should explain why it is unable to launch a new client. ---

I am having the same issue on Ubuntu 10.10. Is there a fix for this. I checked my logs and there is nothing helpful. ---

This is not just a Ubuntu problem, I’ve have it with Mandriva as well. All that’s in the log file is 20 (2 a second for 10 seconds) lines like: NFO | jvm 1 | 2011/01/26 14:19:01 | INFO [VMManager] [14:19:01,190]: VMCreator starting 1 new client VMs. ---

Guys - are these headless linux installs? ---

Ok, we’re going to try a different tack then. From the Gateway’s Configuration section go to the Console, and then to the Levels tab. Find the logger named “Modules.Mobile.VMManager” and change it to Debug. Now try and launch and look at the log. Assuming there are no obvious errors now, it should report exactly what command it is using to launch the mobile VM. You should be able to go into a console and run that command by hand. For example, it should be something like: [tt]java -cp /usr/local/ignition/…[/tt] etc. Run that command in a console and report back with what happens. If this sounds too technical, call in on Monday morning and we’ll walk you through it. ---

Robert - it looks like you’re running an old version. That stack overflow error was fixed in build 6469. ---

Updated to the latest build (b6558), I also upgraded to the latest Java from [www.java.com/en](http://www.java.com/en). I had to manually delete a java dir or two because Synaptic didn’t remove all the old stuff. Now I get: `robert@wiskers:/usr/local/bin/ignition$ java -version java version "1.6.0_23" Java(TM) SE Runtime Environment (build 1.6.0_23-b05) Java HotSpot(TM) Server VM (build 19.0-b09, mixed mode)` And it works ![:thumb_right:](https://us1.discourse-cdn.com/inductiveautomation/original/1X/2026e28c0c425034352c1b75807edf956adc75f4.gif ":thumb\_right:") at least on ubuntu. I can’t touch the Mandrake system until the end of the week.
