Real-time 8.6 Remote panel connection exceeds max number of licenses- with no connections

[maat]

I've been using the remote panel right along with no problems to connect to my Compact Fieldpoint.  This morning I accidently opened the connection twice on the same computer and tripped the "Remote panel connection exceeds max number of licenses" error.  Now it will not let me connect anymore from my computer.  I've tried clearing cookies, cache and history in Internet Explorer and rebooting my computer.  I've fired up the Remote Panel Connection Manager which shows no connections, and the NI License Information window does not show any connections which have been denied due to max # of clients being exceeded.  Is there a way to reset this without having to reboot my RT controller?  I'm running RT8.6 and LV 8.6 Full Dev System and understanding that it should come with 1 remote panel license. 

Thanks

UPDATE: I've tried connecting from another computer and it will not let me from there either.  It still says there are no connections...I'd really like to avoid rebooting the RT controller as it is running an important application. 

Thanks,

The boss wanted to see an updated feature, so I was forced to deploy a new version and reboot.  Problem went away as I suspected it would. 

I did manage to make the same mistake again this morning (launch the remote panel in 2 different MSIE windows) and after closing them both I could reconnect.  Must be a glitch or a bug?  It'd be interesting to see if anyone else has this problem.  For now...solved, but it would be nice to see a way to fix this without rebooting.

Hi Maat,

I stepped into the same problem: LV8.6, LV-RT 8.6, the target is a sbrio, remote panel client is windows xp.

The connection to the remote panel was established, after a firefox/IE-crash the target did not accept any further connection. My application is critical to reboot because it includes security functions, but this was the only solution to get out of that problem.

did anyone solve this problem without rebooting it's rt-target?

kind regards

Sorry, I was never able to find a way to fix it.  I haven't had the problem again, but i've been real careful not to open the link in 2 windows at the same time.  If it happens again and I figure it out, I will post the solution.

Thanks,

Gibbi-

I can’t manage to recreate this on our end.  I opened a remote front panel in several tabs in FF or IE without issue.  I can’t open the same remote front panel in both programs though.  I also opened the front panel in IE and crashed it.  However, I had no issue running the front panel in FF without rebooting the controller. 

Please provide us with some more detail on exactly what happened and what the current system status is.

Hello Mike,

it is also for me not easy to recreate this behaviour.  It looked as if the webserver on the rt-targt did not release one session. is there a internal logfile for the connections of the webserver?

I disabled the webserver and deployed it. When I then tried to connect, it did not work (looks ok). I enabled the webserver again, deployed it, but the message that still one is connected stayed.  I concluded that the webserver did not hang, because it was restartable successfully. 

Do you have other advices for analyzing this issue? What should I test, if i get that again?

Thanks,

Has anyone solved this issue yet?  It seems that several years later this is still a problem.  I am running 2010 SP1 with NI-RIO 4.0 and if I accidently pull up two web pages at the same time (I only have a license for 1) I get the license exceeded error (understandable), but even after I close BOTH web pages and then try and open up the CRIO's web page again the CRIO will not let me back in!  Licenses exceeded error...STILL!.  Is there any way around this other than a CRIO reset?

Thanks
Todd

Hi Todd,

This issue has been resolved in LabVIEW 2011 with the removal of licensing. 

As of 2010, the recommended workaround is unfortunately to restart the target. If possible, I would recommend upgrading to LabVIEW 2011.
