Process with timer and HTTP Service task never finish

Flowable Engine
1

Hello everyone.

I’m facing this issue with flowable platform (files to reproduce in the end of this post). I run 10 instances of my process and usually only 2 are able to complete. The other 8 never complete and have different tasks that never execute. I’ve been trying to make this work for weeks…
I would appreciate very much if someone can help me with this.

For example, this process is stuck in the Task3:

And this othr one is stuck in the Task1:

The process has 5 timers and 5 HTTP tasks in parallel. The request is a simple POST to the request catcher API.

    healthcheck:
      test: curl --fail http://localhost || exit 1
      interval: 60s
      retries: 5
      start_period: 20s
      timeout: 10s
