Publisher Task Times out after 45 Minutes

Anonymous — Mon, 26 Jan 2026 18:19:17 GMT

We have large batch of non dependant tasks that run overnight and we schedule them all in Publisher to start at the same time.

Some of the tasks take minutes to run, some of them can take over an hour.

Some of the tasks fail with this error:

01/01/2012 02:15:06 Error Failed to allocate a QlikView Engine.

01/01/2012 02:15:06 Error No QlikView Engine was available after waiting for 45 minutes

01/01/2012 02:15:06 Error Reload failed because the document could not be opened successfully. DocumentState=CouldNotGetSlot

01/01/2012 02:15:06 Error Reload failed. Distribution skipped.

01/01/2012 02:15:06 Error The task "QV Instrument Dataload" failed. ErrorCount=4

It looks as though once a task has been scheduled if it doesn;t get allocated and engine within 45 minutes it fails.

We have set "Max number of simultaneous QlikView engines for distribution" to be the same as the number of CPU cores and don;t want to set it a ny higher.

How can we raise this default 45 minutes and allow the submitted, pending jobs to run as and when an engine becomes available.

Thanks

You can change limit in

C:\Program Files\QlikView\Distribution Service\QVDistributionService.exe.config.

The key is "QvbWaitTimeoutMinutes".

The general recommendation is no more than the number of cores on the machine. If you are running reloads on the same box as QV server, you'll probably want to go with less than the number of cores so you can save some juice for Users. Unless of course, all your reloads are hapening during a period when no users are on.

If you set more than 7 reloads, be sure to apply the Desktop Heap registry change.

Great advice and will sort out issues with my server - when changing these variables does the server need to be restarted?

Thanks.
