+indicate?</b></a><br>
+The srun command normally terminates when the standard output and 
+error I/O from the spawned tasks end. This does not necessarily 
+happen at the same time that a job step is terminated. For example, 
+a file system problem could render a spawned tasks non-killable 
+at the same time that I/O to srun is pending. Alternately a network 
+problem could prevent the I/O from being transmitted to srun.
+In any event, the srun command is notified when a job step is 
+terminated, either upon reaching its time limit or being explicitly 
+killed. If the srun has not already terminated, the message 
+&quot;srun: Force Terminated job&quot; is printed. 
+If the job step's I/O does not terminate in a timely fashion
+thereafter, pending I/O is abandoned and the srun command 
+exits.</p>
