Qv.exe appcrash

[gandalfgray]

Hi

This applies to QV version 11.20.12235.0 (11.20.SR5) on a 64bit server.

I have a recurring problem where certain qvw files crashes at startup.

They are set to reload using a command file called by the windows scheduler at a specific time.

There is nothing wrong with the qvw:s or command files per se, since if I start any of the command files manually, or opens the qvw:s and runs them interactively, they do not crash.

When I recently changed the time they should be started by the scheduler they also did not crash.

The qvw is set to generate log file, which it normally does, but when the crashes occur no log file is created.

Has anyone else experienced something similar? If so, did you find the cause of the crashes and a solution?

PS

Errors are logged in the Windows event logs, they normally shows the statuscode 0x40000015 (which means STATUS_FATAL_APP_EXIT) or in a few cases 0xc0000005 (which means EXCEPTION_ACCESS_VIOLATION)

Thank you Javier.

I know it's a long time from 2014 until today, but maybe someone might find it useful.

I also experienced "hanging" processes when running reload processes from the command line (cmd / r) with multiple processes simultaneously.

After a very long discussion with Qlik Support, I found myself a workaround (about which Qlik Support said they could not recommend it) : blocking access to the registry key [HKEY_CURRENT_USER\Software\QlikTech].  Full deny on the Windows user that starts cmd process. This solved our problem.

Hi Mihai!

Thanks for your tip!

Interesting, I will try this at some time.

Is blocking access to the registry key done by checking the "Deny" boxes?

[mongolu]

Yes, by checking the deny boxes.

We've done this step (workaround) in late 2013. Since then we didn't experience this problem anymore and didn't notice any side effects.

[gandalfgray]

OK, thanks!

btw what version are you on?

[mongolu]

11.2 SR 8

[gandalfgray]

Ok Thanks, I am on 12.0.2 nowadays.

I got a swarm of these crashes this night , I will apply your fix Mihai, and see what happens!

[mongolu]

Did it solved your problem?

[gandalfgray]

It is a bit hard to say yet.

There has been no crashes since I applied the fix, and I have not seen any negative side effects,

but sometimes it has been several weeks between the errors.

Often they have occurred the first week of the month.

So if I still have no crashes after first week of september, I wil mark your answer as correct!

Yesterday morning a series of QV-applications crashed, so unfortunately the Mihai-fix did not work for us !
