Application hang Lookout 6.2 (Build 49153)

[darick]

NI Support,
I have been having some problems with two different computers with
lookout hanging up. "Application hang lookout 6.02" I have never had
this problem before on any computers we have set up. Could you see if
you have had any problems with this version of lookout or any ideas on
what may be causing this application to hang? We are using Dell
computers Optiplex 760. All diagnostic tests on ram, memory, drivers,
have tested great.Any help would be appreciated. Is this happenning only with lookout 6.2 if so I coud downgrade to 6.1?
Thanks
Darick

Is it lookout 6.2 or 6.0.2?

When does the hang happen? Does it happen every time you open the process, or usually during the running?

Could you upload your process files to ftp://ftp.ni.com/incoming? I want to run your process on my test machine.

Ryan,

Its Lookout 6.2. The hang only happens after the process runs for extended periods of time.

The question posted here is very close to what I have seen only we are not running any other programs on this computer." What is crazy about this is that it will run with no problems for weeks at a time and then it will hang up...

I had the same problem with my application. 

I traced the problem  to the Control Object : Alternator, "Response" Connection.  An unexpected input on the response connection, such as a pump being manually started at a remote location, would crater the program (5 out of 10 times).  I simply stopped useing the object input...

I don't know what other objects use similar logic...

I have had this issue with XP, Vista and Windows 7.  This peculiar application runs on Vista and has been flawless since then....

I'm aware Vista and 7 are not supported.  I'm anxious to try 7 in the XP mode...

PS

Make sure you shut off all windows firewalls, screen savers, power savers, auto-updates etc... These all seem to cause operation issues.

We have fixed a bug in Alternator object. An incorrect input to the Alternator parameter may cause the hang on it. This object doesn't have format check on parameters.

So please check you process if you have Alternator object in it.

No im not using an animator object. Im using a very simple process of two modbus masters, two modbus slave's and trending one analog on each of the two modbus masters.

I am having the same issue. The process runs for a while and hangs up. The error code I get from Windows Event Viewer is: 0000: 41 70 70 6c 69 63 61 74 Applicat 0008: 69 6f 6e 20 48 61 6e 67 ion Hang 0010: 20 20 6c 6f 6f 6b 6f 75 lookou 0018: 74 2e 65 78 65 20 36 2e t.exe 6. 0020: 32 2e 30 2e 34 39 31 35 2.0.4915 0028: 33 20 69 6e 20 68 75 6e 3 in hun 0030: 67 61 70 70 20 30 2e 30 gapp 0.0 0038: 2e 30 2e 30 20 61 74 20 .0.0 at 0040: 6f 66 66 73 65 74 20 30 offset 0 0048: 30 30 30 30 30 30 30 0000000 This has happened several times and I cant trace it back to any object or specific event in Lookout. It appears to be random. I am using the Alternator object in several places but nothing is tied to the "response" feature of the object. Ryan, this is the same process where my ActiveX objects disappeared. I followed the instructions you gave me in the email. Unfortunately, I had already removed the ActiveX controls and replaced them with the "switch" object in Lookout so Im not sure if it would have worked or not. I have a temporary ethernet modbus slave object in the process and I dont remember having this trouble before I created that. It is actually being polled through the network by a modbus master from Lookout Direct. We are going to be moving wires to the PLC very soon and I can delete the temporary connections but I would like to know if that is the problem before moving the wires. If the modbus master/slave connection is not the source of the application hang, then I need to figure out what is before I move the wires permanently. Any help on this would be appreciated. Brian T.

Please send me your updated process. The one I have still uses the ActiveX object and doesn't have the Modbus Slave. I will try to run it on my computer to reproduce the hang.

The error code generated by Windows doesn't help much.

I may have found what my problem has been. I have found a problem with a serial card driver that I am going fix.

I will let you know if I have any more problems.
