Actor Framework Message Maker crashing LabVIEW

BillMe — Fri, 01 May 2015 00:41:37 GMT

Over the last several days there must have been 15 crash reports sent to N.I. Apparently, whenever I use Message Maker, I have a 50/50 chance of it working without causing a major malfunction and crashing LabVIEW. When it does work and the new VIs pop up, there is also a good chance that the next time I run my application, it will crash.

Is anyone else having crashes using the Message Maker? Maybe it just doesn't like me...

LV2014 SP1

The last crash message I got stated:

Access Violation: 0xC0000005

Possible Cause: C:\Program Files (x86)\National Instruments\LabVIEW 2014\vi.lib\ActorFramework\Message Priority Queue\Obtain Priority Queue.vi

This was after I ran Message Maker and then ran my application. Like I said...50/50 chance.

If I don't run Message Maker but do make lots of changes (recode) and then run my app to test, no crashes.

While I have had some crashes after using the message maker, it certainly wasn't 50 percent of the time...

My actor framework got corrupt at some point and message priority queue was no longer part of the actor framework.lvlib as a result. Is you actor framework lvlib OK?

Do you have anything you wouldn't expect to see in your dependencies?

If you take a fresh project and create an actor and use the message maker, is it still 50/50 crash?

Good luck,

Danielle

The only dependencies I have are from vi.lib.

I'll try a new, simpler project see what happens. My current project is starting to get up there in size (444 files)

Ok, I created a new Actor Framework project, created a public VI, ran Message Maker...worked. Created another new VI, ran Message Maker.....crashed:

Exception: Access violation (0xC0000005) at EIP=0x00C681A6

Version: 14.0.1 (32-bit)

Possible Cause: C:\Program Files (x86)\National Instruments\LabVIEW 2014\vi.lib\SourceControl\sccconnsrv\SCC_ConnSrv GenDoneEvent.vi

So, large project or small, the problem persists.

By the way, my installation of LabVIEW 2014 SP1 is hardly two weeks old. I have been running another project (non-AF) without any problems.

Hi,

I doubt it has any connection, but did you install the f2 patch? Perhaps try uninstalling labview and installing again? This sounds like a fundamental problem of your LabVIEW, have you tried asking NI for support?

Re: Actor Framework Message Maker crashing LabVIEW

BillMe — Mon, 04 May 2015 09:38:37 GMT

I have Service Pack 1....that came after the f2 patch didn't it?

I planned to call N.I. support if my problem didn't get resolved here. Guess it's time to do that.

Yup. Sorry I couldn't help.

Do any of the messages you make invoke methods that take a class as an input (other than the actor that owns the method)?

Re: Actor Framework Message Maker crashing LabVIEW

BillMe — Wed, 06 May 2015 08:49:29 GMT

That would be a no.

Re: Actor Framework Message Maker crashing LabVIEW

justACS — Wed, 06 May 2015 15:07:31 GMT

Drat. There was a known issue in the AF project provider in such circumstances. This would be something I haven't seen yet.

It would be interesting to know if your problem follows if you switch to the project provider.

I'm not sure what you mean by "project provider".

Re: Actor Framework Message Maker crashing LabVIEW

justACS — Wed, 06 May 2015 20:40:44 GMT

The Actor Framework Project Provider

Re: Actor Framework Message Maker crashing LabVIEW

BillMe — Wed, 06 May 2015 20:46:08 GMT

I will install and try it. Hopefully it's fortuitous because my app is at the point where my next step is to create a lot of messages.

Re: Actor Framework Message Maker crashing LabVIEW

BillMe — Wed, 06 May 2015 21:17:49 GMT

So on my first try I got this:

Error 1026 occurred at Invoke Node in Actor Message Maker Provider.lvlib:Create Message Classes for Actor.vi:1700002->Actor Message Maker Provider.lvlib:Item_OnCommand.vi:7170001->Actor Message Maker Provider.lvlib:Item_OnCommand.vi.ProxyCaller

Possible reason(s):

LabVIEW: VI Reference is invalid.

Rebooted. Tried again...same error. Happens as soon as I select "Create Messages for Actor".

Re: Actor Framework Message Maker crashing LabVIEW

justACS — Wed, 06 May 2015 21:34:36 GMT

The only invoke node in that VI gets all descendents of the selected library. You shouldn't be able to select Create Messages for Actor if the object is not an actor, so I don't know why that would fail.

How big is your project?

Re: Actor Framework Message Maker crashing LabVIEW

BillMe — Wed, 06 May 2015 22:20:01 GMT

About 4MBs zipped.

And I opened the "Simple Actor Example" that I got from somewhere and the Project Provider works fine. So logic would say there's something about MY project that's causing the crashes.

Re: Actor Framework Message Maker crashing LabVIEW

justACS — Thu, 07 May 2015 15:37:19 GMT

That's what I'm starting to wonder. As I intimated before, there is a known issue with methods that take classes as inputs - that introduces an instability that will cause a crash the *next* time you try to create a message. That's getting fixed in 2015. But what you're describing doesn't match anything I've seen to date.

Put together the smallest version of your project that exhibits the behavior, and a detailed description of how to reproduce it. I will pm you with where to send it. No promises, but I'll see what I can find out.

Another symptom:

I run Message Maker but don't actually build any messages. Close the window.Close the project.

and......

CRASH:

Possible Cause: C:\Program Files (x86)\National Instruments\LabVIEW 2014\resource\dialog\GSW\GSW.lvlibp\1abvi3w\resource\dialog\GSW\Classes\Feed_link\GetCachedFeed.vi

This happens everytime I go through those steps.
