Labview Error 1122
So, the launcher is not responsible for dealing with this reference. My guess is that Labview is not dequeing the elements fast enough. Note: This code will hang if there is no timeout argument provided to the Dequeue Element node. Thanks for the thoughts and keep em coming. http://distributedsimulation.com/labview-error/labview-error.html
Plus I'm using Named Notifiers so it doesn't matter what order they are created. I think the LV engine get 'confused' and screws this up. I am at a total loss. So, there are many many instances of this queue (all unique, supposedly) that exist within each tree of reentrant VIs. http://digital.ni.com/public.nsf/allkb/10AE5BC4A92626058625780600749827
We get error 1122 all the time, because we kill the queues on purpose to stop our processes, but it never happens unexpectedly.

not only would you have to allocate millions of queues, you'd have to have them all continuously in play in order for the refnums to ever hit up against each other. thanxs 0 Kudos Message 5 of 11 (3,050 Views) Reply 0 Kudos Re: Release Queue error becktho Active Participant 07-24-2006 04:09 AM Options Mark as New Bookmark Subscribe Subscribe to What is the difference?

Please try the request again. Without someone actually inspecting the code, there's no further recommendations that I can make, but those are two independent subsystems, so I would be very doubtful of a bug caused by I thought labVIEW used a GUID to name unnamed queues so they could never step on each other, but maybe because I have so many, the 'name' is getting reused? As you can see from the error, the 'main.vi' has been spawned from a template 422 times and the reentrant subVI that got the error is one of 34 in memory
The error pops because you left the error out output unwired. In your previous code, that error travels all the way to the Simple Error Handler, which is the function that pops up the dialog box. There's an assumption that customers have to get their architectures down small before a bug will get investigated. Here's an alternative approach. ___________________Try to take over the world!
I use a number of queues and parallel processing some of them with high speed data with very few problems especially on Labview 8.5.1 Have you tried mass compiling your entire http://boardreader.com/thread/why_do_i_get_error_1122_at_dequeue_eleme_5k44X1v78d.html I think there is a bug in the code that manages refnums.

If you don't declare the size of the queue Labview has to constantly allocate more memory for the newly acquired data. this contact form Generated Wed, 30 Nov 2016 23:42:06 GMT by s_hp84 (squid/3.5.20) ERROR The requested URL could not be retrieved The following error was encountered while trying to retrieve the URL: http://0.0.0.10/ Connection
In order to get any recycling of the unnamed queue IDs you would not only have to generate roughly 30 million queues, you would also need to get particularly (un)lucky on In another whileloop I dequeue the elements.The vi works fine, but when I stop it appears two "zeros" in the Line indicator. I am able to interact with it even after the error is reported.
I handled with the problem.
You destroy the queue in the top loop. I get the following errors from this VI: Error 1122 occurred at Dequeue Element in BIG-IP_TESTS_TM Get Scheduler Response.vi:21->BIG-IP_TESTS_TEST Call Scheduler.vi:9 Possible reason(s): LabVIEW: Refnum became invalid while node waited for I thought labVIEW used a GUID to name unnamed queues so they could never step on each other, but maybe because I have so many, the 'name' is getting reused?

Your wait ... What it boils down to is LabVIEW is corrupting its own memory when running large parallel apps with a lot of shared clone Vis. All rights reserved. navigate here It reads data in large chucks but uses immediate mode with a timeout of 10ms.
Use the get queue status vi to monitor the queue. The work-around it to make sure the VI's that creaed the queue don't go idle until after the queues is destroyed. Is there a way?

For more informaton and to subscribe to the email list and a topic linked search of archives at "http://sthmac.magnet.fsu.edu/infolabview" You have used invalid URL paramaters to request a page. Are you using the "destroy" input for the Close Queue function? I hope they can offer me a work-around. Even if the VIT was stopped by an external VI, this error would never happen and the code that logs the error to the event log would also not execute.
Always ensure to close the reference only after all other functions needing it have executed.

The wierd thing is, as far as I know, this can ONLY happen if the queue is destroyed in some parallel process while this VI is waiting for an element to When I see this, my app is using about 100MB. crossrulz 2 user's latest post: why do i get error 1122 at... Also try declaring the size of the queue and check the queue to see if it is full before you enqueue another element.

It displays the status of each of the spawned VITs and allows you to view their FP via another VI with a sub panel. You destroy the queue in the top loop. newbieeng Active Participant 05-28-2013 12:29 PM Options Mark as New Bookmark Subscribe Subscribe to RSS Feed Highlight Print Email to a Friend Report to a Moderator Ok thanks.
