    [ The following text is in the "ISO-8859-1" character set. ]
    [ Your display is set for the "ISO-8859-10" character set.  ]
    [ Some special characters may be displayed incorrectly. ]

Please provide SGE version (update level), OS version...

Also, shepherd is started by execd... thus the shepherd can inherit
the limit from it. So, is the execd started by the rc scripts?? And,
is there a limit set there??
