What do {script,stdout,stderr}.kill files indicate?

If {script,stdout,stderr}.kill files are present in a task's execution directory, does this indicate that Cromwell has intentionally killed a task due to some error condition? If so, Is this error condition necessarily related to the killed task?

    Cromwell does add the "kill" extension to those files when a user tries to abort a workflow when using certain backends. Did you or any other user try to abort a workflow while it was running?

    Could you also explain what environment you are running Cromwell in, namely what backend you are using.

    This is running on an LSF backend. I have an error message about running out of memory for the parent Cromwell job with 12 GB of memory, which results in LSF killing the parent Cromwell job. I am trying to determine whether the .kill files for the task also indicate there is a problem with the task resource allocation, or if the problem simply stems from the parent resource allocation.

    Yes, the Cromwell parent job runs the java process running Cromwell. The Cromwell server is running in single workflow mode.

    Great that means what I said earlier still holds. Your Cromwell resources are the cause, not your task resources.
