I run an independent job on a local cluster. If one of its tasks fails, the task property Status is set to 'finished' and the task properties Error/ErrorMessage/ErrorIdentifier contain information about the error. Sometimes, however, Status is set to 'failed' and Error/ErrorMessage/ErrorIdentifier are empty.
What does the failed status mean and when/why does it occur? When it happens, how can I determine the reason of the error?
Thank you.

This can happen if the worker crashes when processing the job. You might be able to get more information like so:
c = parcluster();
j = createJob(c, ...);
t = createTask(j, ...);
c.getDebugLog(t) % gets more information about the task 't'
