Camunda Timer Boundary Event Not Working Correctly

Hi everyone,

I’m trying to use a non-interrupting timer boundary event on a user task to send notifications. My goal is to have the notification sent four times, every 20 seconds. I’ve attached a screenshot of my current setup.

However, the timer behaves inconsistently across different instances. Sometimes it triggers at random intervals, and other times it doesn’t repeat the full four times.

What am I doing wrong?

It’s likely do with how often the job executor polls for work.
There’s a great blog post written on the subject here which should give you an idea about how to set the engine to ensure that it polls as frequently as needed
