When multiple processes start at the same time, not all of them run

Hello!

When I start 5 processes via REST API at the same time in integration tests, not all of them run.

I use:

  • Camunda 7.17.0
  • Camunda Spring Boot Starter
  • All tasks are run as External Tasks

My questions:

  • What is a probable cause of this misbehaviour?
  • Are there parameters to change in Camunda to influence on this behaviour?
