GP task failed but won't stop running

[RayaKogan]

I'm running an async GP task from a widget.. 

When one of the params given to the GP is wrong (e.g. wrong or inaccessible folder path), in the job messages I get this messages: 

- <GPMessage xsi:type="typens:GPMessage">

  <MessageType>200</MessageType>

  <MessageCode>0</MessageCode>

  <MessageDesc>Cancelled script Groups Cross Section - Web...</MessageDesc>

  </GPMessage>

- <GPMessage xsi:type="typens:GPMessage">

  <MessageType>200</MessageType>

  <MessageCode>0</MessageCode>

  <MessageDesc>(Groups Cross Section - Web) aborted by User.</MessageDesc>

  </GPMessage>

BUT the job status is still on executing, and won't change to failed. Which means my GP is submitting a job after a job and doesn't stop running.
