[fetchmail]Fetchmail error

HI

Suse Linux 7.0

After i installed fetchmail and tested it once, i cannot start fetchmailconf
again. Error is like folllows:

bash-2.04# fetchmailconf
Both fetchall and keep on in daemon mode is a mistake!
`fetchmail --configdump --nosyslog >/tmp/fetchmailconf.890' run failure, status
1280
Unknown error while running fetchmail --configdump

What can i do now.
