we are currently using Camunda Platform 7 with Spring Boot in production and had today the issue that our External Task suddenly hung up and no further process instances could proceed the external task.
The problem could be resolved by restarting the External Task.
I am now trying to understand why the External Task hung up. Sadly there are no logs written that could be used to retrace the problem, neither in the External Task itself nor in the central process with which the bpmn is deployed.
camunda.bpm.client: basic-auth: username: "username" password: "password" async-response-timeout: 10000 worker-id: spring-boot-client back-off-init-time: 500 back-off-factor: 2 back-off-max-time: 60000 lock-duration: 15000 max-retry-timeout: 120000 retry-timeout-init-time: 15000 allowed-delay: 1000 max-amount-of-tasks: 10
- What are typical reasons for this behavior?
- How can I prevent this behavior?
- How can I make it be visible in my logs?
Thank you for any help!
