We have a scheduled reload task that on on several occasions has just failed to run at all, no errors etc, it's almost as if the schedule had been removed.
This task was successfully started for the last successful time:
|3/11/2014 08:37:00.3195761||Information||Trigger detected. Type=Start, Trigger=ScheduleTrigger, State=1;3/11/2014 8:37:00 AM;Triggered;Unhandled, Task=Dashboards/LIVE/xxxxxxxxxxxxxxxxxxxxxxxxxxxx.qvw|
And completed 6 minutes later.
After this happens a 'workorder.ddmmyyyy.txt' file is created which contains the following:
3/11/2014 08:37:32.3155863 Information Executing Task already Dormant detected. Dormant Task will be activated when current Task is finished. TaskName= Dashboards/xxxxxxxxxxxxxxxxxxxxxxxxxxxx.qvw
3/11/2014 08:37:35.4512265 Information Executing Task already Dormant detected. Dormant Task will be activated when current Task is finished. TaskName= Dashboards/xxxxxxxxxxxxxxxxxxxxxxxxxxxx.qvw.qvw
The task never runs again after this untill the 'apply' button has to be clicked on the 'reload' tab of the document. This task, along with several other runs every 15 minutes.
Is there a large number of tasks?
It's possible that reducing the QMS chunk size to 20 would help. The default is 100, and the setting is found here:
"C:\Program Files\QlikView\Management Service\QVManagementService.exe.config":
<!-- Message size for QMS workorder -->
<add key="QMSChunkSize" value="100"/>
