Internet crash

bbi_mba_76 — Fri, 02 May 2014 15:07:42 GMT

Hi,

in my production environment we have several internet explorer crashes when we open the documents with the plugin.

After the crash internet explorer redirect to res://ieframe.dll/acr_depnx_error.htm#,about:blank

Sorry it is an Italian page, but it seems to be related to the data execution prevention:

What I have to check/do?

Thanks very much.

Make sure your Plugin version is the same QlikView version as the QlikView Server. Do you ever get crashes when using AJAX? If no, then double check that nothing is interfering with port 4747.

Hello Michele,

I suspect something is blocking port 4747, make sure all ports are open, may be try with by disabling firewall . You can check for network blocks through telnet command from the client to the server.

Could you also please ensure the version of IE and Plugin once.

Regards

Advait

Hi,

it seems there are no problem with AJAX, but telnet 4747 is ok(blank page).

Hi,

IE is 11, but my colleagues have different version. The plugin has the same version of the server.

Re: Internet crash

jerrysvensson — Mon, 05 May 2014 08:28:38 GMT

Are you running 11.2 SR5? IE11 is supported only from that version and higher.

Re: Internet crash

bbi_mba_76 — Mon, 05 May 2014 08:52:39 GMT

Hi,

yes, we have the 11.2 SR5. But we have the issue also for someone that has the IE9 or IE10.

Other info: the web server is IIS and there is a proxy but it allows localhost

Interesting; sounds like you'll need to enable extended error logging to see what exactly is going on here. Below are the instructions (make sure to have backups before proceeding):

Settings in QlikView 10 and above are stored in a settings.ini file.

Close any running instances of QlikView Developer and QlikView Plugin
Locate the file settings.ini
- Windows XP / 2003: C:\Documents and Settings\<User>\Application Data\QlikTech\QlikView
- Windows 7 / 2008: C:\Users\<User>\AppData\Roaming\Qliktech\QlikView
Edit settings.ini and In the section labeled [Settings 7] add the following line to turn the logging on:
- ExtendedErrorLoggingMode=1
- (To turn the logging off change it to: ExtendedErrorLoggingMode=0)
Save the file
Open a QlikView document hosted on a QlikView Server to generate the log file

The logfile created is called QlikViewError.log and can be found in the following location:

Windows XP / 2003: C:\Documents and Settings\<User>\My Documents
Windows 7 / 2008: C:\Users\<User>\Documents

Few things -

Does it happen every time you try to use the IE Plugin?

Does it happen with every document (QVW) when used with the IE Plugin?

When did it start?

Were there any changes to the system (upgrades, updates, policy changes, etc ...)?

Can you copy and paste the error so we can translate it? (There might be more information)

It happens randomly using the IE Plugin, in all the documents

We have this problem starting from december and we see errors also in the event log of the server

The description for Event ID 300 from source QlikViewServer cannot be found. Either the component that raises this event is not installed on your local computer or the installation is corrupted. You can install or repair the component on the local computer.

If the event originated on another computer, the display information had to be saved with the event.

The following information was included with the event:

Server: An exception (T) occured during open of FOLDER/DOC.qvw.

In december I upgraded the qlik server from 11.20 SR4 to SR5

Re: Internet crash

iliyansomlev — Tue, 20 May 2014 15:05:51 GMT

Hi Michele,

We experience the same problem with 11.2 SR 5 server. When opening QVW in Plug-in, an error appears that ends with .....QVSTunnel.dll%3Fhost%3Dqvserver could not be opened

If we restart the services, access through Plug-in works again until some time later when the same error appears. (in the log files it says exactly as in your post above ending with "An exception (T) occured during open of ZZZ.qvw"

Did you find a solution for this?

Thank you very much.

Re: Internet crash

pbr — Wed, 21 May 2014 13:18:19 GMT

When QlikView logs out an error into the Events file, it should display the entire error message as a consequence of the exception that has been caught, in the program.
However, some cases in 11.20 SR4 or 11.20 SR5, it just display the first character of the error message in stead of displaying entire error message.

Typically, you can only see a capital T, which does not tell that much about the actual error.

Example: An exception (T) occured during open of Test.qvw

This was fixed in 11.20 SR6 to give the full error

It was intended to show those messages in parentheses.

The file cannot be opened

The file doesn't exist

Possible issues -

Something locking the files - Antivirus/Backups (make sure Qlikview folders and file extensions are excluded) since this error seems to be associated with opening the file itself, but can you verify that AJAX works when this occurs in the plugin under the same circumstances?

Re: Internet crash

bbi_mba_76 — Mon, 26 May 2014 08:25:52 GMT

Hi, in Ajax we don't have the problem.

But we have older docs with many macros and I prefer to have the plugin working.

Thanks

Has there been any resolution to this issue? I have the same issue. QV 11.2 SR12 on Windows Server 2012 R2.

Users experience the issue on Windows7 and Windows8 and with either IE 10 or IE 11.

Any help would be greatly appreciated.

Thank you,

Craig Leite

Hi BBI_MBA_76

Did you resolve the issue?

Hi Arjun,

I have not found a resolution to the issue. We are not experiencing this issue on a regular basis. I have not tracked down the specific conditions before the crash occurs.

Do you have any insight on this issue?

Thank you,
