+Once you have the output of the command you will need to investigate the processes 'State'
+^ State ^ Definition ^
+| D  | uninterruptible sleep (usually IO) |
+| R  | running or runnable (on run queue) |
+| S  | interruptible sleep (waiting for an event to complete) |
+| T  | stopped, either by a job control signal or because it is being traced |
+| X  | dead (should never be seen) |
+| Z  | defunct ("zombie") process, terminated but not reaped by its parent |
+|    | |
+| <  | high-priority (not nice to other users) |
+| N  | low-priority (nice to other users) |
+| L  | has pages locked into memory (for real-time and custom IO) |
+| s  | is a session leader |
+| l  | is multi-threaded (using CLONE_THREAD, like NPTL pthreads do) |
+| +  | is in the foreground process group |
