My pipeline has the following options:

  options {
    buildDiscarder(logRotator(numToKeepStr: '3'))
    disableResume()
    timeout(activity: true, time: 10, unit: 'MINUTES')
  }

However, there is sometimes a timeout, although every few seconds the log is extended. In the case the log says:

Timeout set to expire after 10 min without activity
...
Cancelling nested steps due to timeout
Sending interrupt signal to process
...
Timeout has been exceeded

The timeout occurs always in the Test Stage, during a nightwatch test. The position seems not deterministic. I have 4 nightwatch tests in this stage and I got timeouts at the beginning and also at the end of this stage.

Sometimes the pipeline works as it should and after about 16 minutes the build is completed successfully.
I also changed the timeout time (e.g. 2,3,5,15 minutes) and got similar results.
