I have a reload task say task1 which gets executed successfully everyday but on the QMC/QEMC status it shows failed.
So the task followed by task1 is not triggered,
Here is some portion of publisher task log.

So one thing I would look at is the document log for the file being reloaded. I have found that the task log doesn't do a good job of saying why a task failed, but if you look at the document log it gives the exact point in the file where the task failed on. So first I would make sure that document log is turned on in the file. If it is already turned on then look at the document log, if not please turn document logging on and reload the app. This should be able to give you more information on why the task is failing.
