different behaviour in fg and bg

fg = foreground bg = background
I have a cobol program that I start with a very simple script.
The script is not at fault as it has not changed and the program worked in fg and bg before.
I have altered the logging in the program and moved my cursor declare to working storage.
The program runs as a daemon sleeping and checking every minute if it needs to run.
now when I run in foreground - it works creating the log file and reading the records from the oracle database
when run ./start_script& (in background)
no log file in /tmp
no records selected from oracle although in exact state as those set for foreground test?
Any help appreciated

Regards
Bruce

Hi Experts, ps command behavior in Redhat is such that it outputs all the output(of long lengths). In Unix the ps command output was limited to only 80 chars.

NAME
ncftpbatch - Individual batch FTP job processor SYNOPSIS
ncftpbatch -d ncftpbatch -l ncftpbatch -D OPTIONS
Command line flags: -d Begin background processing of FTP jobs in the current user's $HOME/.ncftp/spool directory. This returns immediately, because a daemon process is spawned and ran in the background. -l Lists the contents of the user's job queue. -D This is like -d, except that the process does not become a daemon. DESCRIPTION
This program is responsible for processing background FTP requests. It is normally only run by ncftp and not manually by a human being, however you can run it to manually process the FTP job queue. The jobs are spool files written to a user's $HOME/.ncftp/spool directory and have a special format and file-naming convention (which con- tains when the job is to be run). ncftp runs this program when it needs to, but if the ncftpbatch daemon dies unexpectedly the jobs that are left in the queue will not be processed until another instance of ncftpbatch is run. ncftpget and ncftpput can also be used to submit jobs for batch processing, using those utilities' -b command-line flag. If desired, you can also manually create the spool files although this procedure is not documented here (see the manual page for ncftpspooler for more information on how to do that). DIAGNOSTICS
ncftpbatch writes to its own log file, the $HOME/.ncftp/spool/log file. This file should be examined to determine if any ncftpbatch pro- cesses are actively working on jobs. AUTHOR
