ftp processes still in process table

[genova]

I run 6 different scripts via cron that ftp files to their particular destinations. I wrote a generic ftp script and modified as necessary for clients SRC --> DEST

Other than destination IP_addresses, user_IDs and passwords, they are identical

ftp -idvn >> $LOG << EOF
open $HOST
user $USER_ID $PASSWORD
bin
put <file> <dest>
quit
EOF

Four scripts run and exit cleanly, but two scripts leave the parent process and child ftp process out in the process table forever. I have to manually kill the PIDs. I have debug on, so I can see a graceful exit when files are sent. I have explicitly put &quot;exit 0&quot; at the end of the scripts.
Any help/ideas/suggestions are appreciated.
