QMC triggered tasks not starting

Mon, 26 Jan 2026 18:19:17 GMT

I have a list of QMC Tasks...each of which are triggered by the successful completion of the previous one. It often happens that a task will complete successfully, but the next task that should start upon that successful completion does not start. There are no other conditions for the task to start. Also, it happens to different tasks at different times on different days. There is no rhyme or reason to this behavior. It seems to be completely random (and, of course, the logs are of no use as they simply show the previous task completed successfully). Any thoughts? Is there a resource of some sort that might be temporarily occupied that the task needs to start? If so, wouldn't there be something in the logs to that effect?

Maybe there are sometimes too many tasks at the same time enabled and/or some timeouts happens - maybe this could give you some hints where you could look: Server-Task delaying

Marcus,

The tasks all run in a "waterfall"...i.e. there are no concurrently running tasks...they all run one at a time.

i.e. they are all "sequential" they do not run in "parallel".

SR2 is quite old and there was many bugfixes since them - the last release is SR12. Therefore I suggest to upgrade your environment.

Thanks Marcus.

One more question. I presume by SR12 you are referring to Qlikview itself and not the QMC. If so, how does that impact how the QMC performs? IF my presumption is incorrect, please let me know. Thanks.

The qmc is part from the qv server installation and therefore it will be upgraded, too and qv server and qv desktop client should be on the same release.

I don't know whether it is bug in the version you use.

But this kind of situation happened to me also once so I deleted all the tasks, restarted the services and recreated them, it worked fine for me by then.
