QMC Reload Now not working

Mon, 26 Jan 2026 18:19:17 GMT

We're experiencing a server-wide issue where no users can reload a QVW using the QMC. The Status tab shows 0 jobs running and when you go to a document (we have tried 5+ different apps) and hit Reload Now, nothing seems to happen. The log file is not updated and the job never hits the Status tab.

We tried restarting the server yesterday, but the issues are persistent. Multiple users are experiencing the same issue.

Thoughts?

The TaskLog for the job showed it completed successfully, but then had the following error at the end:

12/10/2014 12:04:08.0000410

Error

Exception=System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.ArgumentException: An item with the same key has already been added.

After we rebooted the server it shows a job was running on the Status tab, but when I right-clicked on it I got the following message:

There was an inuse file in the Log folder prior to rebooting the server, but it is not there any longer.

Hi,

Try to delete and create again the task. Usually it works.

Are you getting the same error when you create a new job for a new application or does it only happen on legacy jobs/applications?

For those experiencing this error, I found this post helpful.
