Description

We have found that IntermediateCatchEvent with duration of 10 seconds or so often do not fire. I read online this is a known issue. Online folks had two workarounds.

The first was to set this in process-engine:

<property name="jobExecutorDeploymentAware">false</property>

That seemed to help just a bit but it did not fix the problem.

The second suggestion was to set the timer duration to 1 minute or more as they stated shorter duration are not supported well in Camunda. So I set the duration to PT1M and that did fix the problem...all expected timer events did fire.

However then I found a second bug...the PT1M duration actually fires about every 15-20 seconds not every 60...so its clock is off by a factor of 3-4.

Note that in my BPMN the timer is in a parallel multi instance sub-process. But it was only processing one item in the collection.

We do require shorter time duration of a few seconds so need to know how to fix this.

Here is an example of the sub-process.
