Scheduled tasks sometimes completed, but most of the time failed

[Anonymous]

Hi All,

Attached files are log files from the same QVW file (ReportingSection), one failed (09 Jun 2015 2:08 PM) and one completed (09 Jun 2015 2:41 PM). Snapshot between these two log files in below:

09 Jun 2015 2:08 PM --> failed

09 Jun 2015 2:41 PM --> completed

I have done the following:

- restart server

- restart all services

- remove and put back the tasks

- check the ODBC setup

Additional information:

Looking forward for your advise what need to be checked to solve the above error.

Thank you in advance.

Best regards,

If it runs fine at once and it failed in another instance then it may be because of the server load.Check how many jobs are running during the time you scheduled your job.I hope there is a limitation of the jobs scheduled.

Hi.

Verify if database loses connection to the networking during load.

This error  "QVX_UNEXPECTED_END_OF_DATA" happens when there is crash.

Hope it helps!

Hi,

verify if other applications/batch are running when you get the error and if they require/cause a db lock.

It seems that something is using the db when you are loading your qvw.

Let us know.

Your SQL Server database is dropping connections (connection closed by remote host). This could be at random (network errors) or systematically (meaning that your SQL server is in trouble)

Two questions:

• Is SQL Server running on the same machine as QlikView Server (I expect not)
• "... most of the time failed" Do tasks always fail with the same error?

SQL Server also has log files. Ask your dbadmin to check these logs for any additional messages.
