Check the document log for errors. The document log will be in the same directory and have the same name as the .qvw document with .log appended.

Thanks for the reply. It doesn't show any errors. The last line in the screenshot is the end of the document.

Check that your system did not run out of memory.

It could be that it timed out. Check the Timeout value in the trigger definition,

Hi Rob,

The reload was successful a day ago, although it took around 19 hrs. It failed after running for around 16 hrs in this instance. Since we haven't changed the timeout settings, I am ruling out the possibility of a time out.

We have over 700 GB of memory on that server, and the RAM is also more than 96 GB. and we have enough free space.

Thanks,

Karan

Is 96 GB the amount of ram in your machine or is it 700 GB and is the document size 96 GB? Reloading a document may require more ram than the size of the resulting document. This is because temporary tables may be calculated that will be discarded later in the script. Also the .qvw document could be stored in a compressed form. In ram it will be uncompressed.

the RAM is 96GB.. the qvw file size is aournd 250MB only.

Rob is correct. The message "Killing the Qlikview Engine" Means either the task timed out, the task was aborted manually, or the process was killed on the server.
