Timer behaving weirdly

We’re in the process of evaluation Camunda and we tried a very simple workflow that is started by a timer.
The timer is supposed to fire every 2 minutes. This seems to work fine right after deployment but after a while the events randomly stop.
What are we missing? Could this be related to the httpconnector we are using?

What is your setup?
Spring boot? H2 Database?
when does it occur?

We’ve deployed the camunda-bpm-tomcat-7.12.0.tar.gz distribution on centOS 7 and connected it to a MS SQL server database.
The workflow worked fine yesterday up until we shut down the server. After a restart this morning camunda came back up fine and everything is accessible but the timer never started creating process instances again.
What are the components we should take a look at here? Are some job execution routines not being restartet properly? Any way to monitor this in the database?

Sounds like it’s probably related to this issue https://jira.camunda.com/browse/CAM-9434
You can try to use the fix suggested in the comments.

That did the trick. Thanks very much
