I have a QMC task that runs every day and normally takes around 15 seconds to complete. Recently however it seems to hang every few days and doesn't complete until we cancel it.
It's a query running against a MYSQL database and we can see the query from the database, but there don't appear to be any rows being returned.
I had the same issue running the task directly on the Qlikview server so it doesn't appear to be an issue with QMC. When I copied the live qvw and tested in our development area it worked ok, so I removed the initial qvw and replaced with the development version which resolved the problem, but a week later it started the same behaviour. Has anyone else experienced this issue?
