    [ 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. ]

More info is needed:

1) is there a way to specify the location of the log file?? Is so, are you
using the same location for each job??

2) if each job can write to a unique location (eg. using the Job ID to make
it unique), then you can run another job to merge the results at the end of
the day (or periodically).
