           Summary: If 'args' is specified as a column name to 'ps -o',
                    any column names given after args are ignored
           Product: Busybox
           Version: 1.19.x
          Platform: Macintosh
        OS/Version: Mac OS
            Status: NEW

According to the help text when typing 'ps -o meh', supported column names are: 

user,group,comm,args,pid,ppid,pgid,tty,vsz,stat,rss

These can be specified in any order or combination and work correctly, EXCEPT
when 'args' is specified as a column name. When this is done, no column names
given after it will be shown.

So, typing 'ps -o user,group,comm,pid,ppid,pgid,tty,vsz,stat,rss,args' will
show all columns, as 'args' is last in the list. However, re-ordering the same
parameters so 'args' comes earlier will break. For example, 'ps -o
user,group,args,comm,pid,ppid,pgid,tty,vsz,stat,rss' will show only the
user,group, and args columns.

The placement doesn't matter... whatever comes after 'args' fails to get shown. 

Incidentally, the same holds true even when specifying the -o parameter
multiple times. This shows 3 columns, user, group, and args:

ps -o user -o group -o args

Whereas this shows only the args column:

ps -o args -o user -o group

I'm running BusyBox v1.19.3 (2012-02-21 15:37:53 WET) multi-call binary on my
D-Link DNS-323 NAS box.
