Access Violation after upgrading to NT14.04 from NT 12..

[Richard I]

Hi
I have an Access Violation following a successful compile and gzipall in NT 14.04 after upgrading from NT 12...
when run in Deployment mode.
If I compile and run in Development mode it runs OK
The Exception Log is attached
Thanks

Hi Richard,

     I'm getting essentially the same when running the Multi-site host exe.  Will try Jane's suggestion but all this worked with NT 12.61.  No changes to this app when moving to NT 14.04.

Jeff,
I've only experimented briefly with multi-site host, so just speculation here. 

Have you made sure to compile all the NetTalk sites with the same version of NetTalk that you're using for the host?
Will the host run by itself?
Will the host run with just a static site (such as with the multi-site example app)?

Is yours like Richard's situation - his runs in debug mode but crashes in deployment mode?  If so, another thing to try would be one-by-one enabling the different items that get set by switching to "deployment" and seeing if you can isolate the crash down to one switch.

Thanks Jeff,
Good to know, Im not alone
which suggests its an internal  NT issue and not necessarily something Ive done.

Frustratingly,  Ive got an upgrade waiting to send -
I believe that  NT is backward compatible -ie can I install NT 12.64 over the top of NT14.04?

Cheers
Richard

[Richard I]

Thanks Jane Ill do that....
 seeing you are on line - can i over install 12.64 on top of 14.04 safely?

Following Jane's suggestion -

In Deployment Mode
By Changing "Compress dynamic data" FROM True To  False removes  the  Access Violation
All other settings in Deployment are the default.

So "Compress dynamic data" is the apparent problem

Thanks Jane, again !
Ill await edification
Cheers

Hi Jane and Richard,

     Both the multi-site host and the dll apps are compiled with NT 14.04

     The multi-site host does run by itself and I can use the static web app to manage it and add dll apps.  However, upon saving, the multi-site host crashes
     with the same access error Richard receives.

     The dll apps, when compiled as an exe and run as a standalone web app server, I can connect to and run the app as expected.

     I tried changing the Compress dynamic data option but it does not help.

     When I start the multi-site host with one or more dll apps added, they are automatically made inactive.  The error tab on the multi-site host has:  DLL
     Caused Error - automatically made inactive.

     I'm lost here, as these dll apps compile and run in NT 12.61.

     Any other thoughts on things to check?

Thanks,

Jeff King

Hi Jeff,
Id be inclined to sit on it until  Bruce replies.  he's at Conference currently 
Meanwhile, Im living with an amended Deployment

Hello all,

I have compiled the multi-site host and one dll app using debug mode and the debug version of ClaRun.dll.  Attached is the error log.  I noted that the ClaNet.dll for NT 14.04 shows the Clarion version 11.01.13733.  Not sure if this is significant.  Anyone have any thoughts on this error log?

Thanks,

Jeff

     The solution was that the deployed dll app has it's own set of required dll's.  These also must be included in the host.exe folder.  I don't know the exact dll name that was the problem, I simply copied all dll's from the dll app folder into the host.exe folder and the exception error went away. 

     Note that the other symptom here was that when I started the host.exe, the deployed dll apps would be set as "inactive".  It seems the host.exe will check the deployed dll's on startup, to determine if they are "good" or not.  Perhaps Bruce can explain this process a bit as it would be interesting to know.

Thanks,

Jeff

Hi Richard,

So I take it, for you, it's still failing in Deployment mode, but all ok in Development mode?
If so, try changing the performance tab settings a few at a time to narrow down which setting might be in play.

cheers
Bruce

[Richard I]

Hi Bruce,
Thank you
Yes, development Mode does compile and run OK
Earlier in the thread I reported that:
If in Deployment Mode  "Compress dynamic data" is changed   FROM True To  False
and All other settings in Deployment are the default,
The Exception or Access Violation report does not appear
So "Compress dynamic data" is the apparent problem

With the setting at True, being the default,  it does display.

In the post immediately prior to yours in this thread, I have displayed the Call Stack information, which I hope might help,.
Regards,
Richard

Hi all,
Pleased to report that with Bruce's help, Ive solved the GPF issue reported here.
It required me to change in the project to dll mode and clean out some of the dlls in the folder that were not needed.

Now in the performance tab Deployment, all settings are set as TRUE

Thanks Bruce
Richard
