Just an update.
After schedule the dash to different time, an early and later time. The problem is gonna in 3 days.
As all the rest 2 daily reloads never has this issue, really think that is something wrong at the time of the issue reload.
But can not figure it out as there is nothing even suspicious in the server after investigation with our IT manager.
From reviewing the document log, the reload looks to have hung. Can you also provide the task log from the same timestamp from the reload engine/publisher?
Based on your last statement, the reload was successful after it was scheduled for a diffenrent time? Can you confirm?
Thanks for your reply.
I guess the same reason as you after checked the log, and after change the time, yes, it works like a charm.
So I double checked the windows schedule. (We do not use QMC to schedule the reload task, but use windows schedule as more operations needed after the dash reload. )
And later I found the reason. We have a task to kill all the hanging process to solve a issue long time ago. And as the dash grow, the reload time now overlap with that killing process task. So the reload process dose not hang, but was killed.
At the same time, the Windows task manager can not detect this case correctly. The history still shows the QV reload process start and complete correctly. So that is why it is confusing me at first.
As you're not using the QlikView Reload Engine/Publisher, there won't be a task log to consult, so I really can't offer much of an informed comment regarding the root cause. One thing I can think of was that there were too many concurrent tasks scheduled, resulting in contention for the available reload engines. Have a look in the QMC > System > Setup > Distribution Services > QDS@ > Advanced tab to check and see how many simultaneous QlikView engines are set. Whatever the value is here, if there are more concurrent tasks scheduled for a particular time, some will have to wait for available engines. Sorry, but this is the best I have given the information.
Hope this helps,
