Forum Linux.débutant erreur mrtg

Bonjour
Pourquoi est-ce que j'ai ça ?

ERROR: I guess another mrtg is running. A lockfile (/home/ovh/www/mrtg/mrtg-sys/mrtg_nsxxxxxx.ovh.net.cfg_l) aged
227 seconds is hanging around. If you are sure that no other mrtg
is running you can remove the lockfile

et aussi ça :

/etc/cron.daily/0logrotate-webalizer:
...
Error: Unable to restore run data (1)
...
sudo: no passwd entry for domaine.tld_sd_abcedef!
...

Merci d'avance
