title: Solution to work disk space not enough in sas
body: <p>I have more than 50 tables running in work. Before, it worked well. 
  But recently, there are some errors like: </p>
  
  <blockquote>
    <p>ERROR: An I/O error has occurred on file
    WORK.'SASTMP-000000030'n.UTILITY. ERROR: File
    WORK.'SASTMP-000000030'n.UTILITY is damaged. I/O processing did not
    complete. NOTE: Error was encountered during utility-file processing.
    You may be able to execute the SQL statement successfully if you 
          allocate more space to the WORK library. ERROR: There is not enough WORK disk space to store the results of an internal sorting
    phase. ERROR: An error has occurred.</p>
  </blockquote>
  
  <p>Does anyone know how to solve this error? </p>
