Problem Description
Hi,
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.
External Task Config
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
Questions
- 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!
