Hi Jonathan,

> because of this line:
>   cat ${INPUT} | while read SITE HOST SIZE_ARG FLAGS; do
> Since the while loop is in a pipe, it's executed in a child process.
> As a result, its child processes, i.e., the ones running innxmit,

> doesn't wait for them.

Well, many thanks for your comments and the fix.  Very much appreciated.
It will be included in the next release (INN 2.6.1).
