chose bizarre sur mon serveur qui m'a vallu un reboot manuel
Bonjour,
D'un coup y'a deux jours, le serveur imap de mon serveur etait assez
lent depuis un autre poste de mon réseau et donc en faisant un top/htop,
j'ai vu ceci:
9825 root 25 0 4908 1908 1280 R 89.4 0.2 64h37:05 proftpd:
216.85.121.28:5924
J'ai été assez etonné, et le pire, c'est que même en faisant un stop sur
proftpd, et killall proftpd, bah ca restait tjs là lol.
Depuis le reboot, tout est rentré dans l'odre.
Voila ma config de Proftpd:
-------------------------------------------------------------------------
# cat /etc/proftpd.conf

# /etc/proftpd.conf -- This is a basic ProFTPD configuration file.
# To really apply changes reload proftpd after modifications.
