Fins ara a la feina ja m’havia acostumat a veure systems loads del voltant de 30-40 o més, sense massa temps per mirar que passava i total la màquina seguia anant, a patades, però funcionant.
Avui m’he sorprès. Al intentar accedir al servidor he vist que estava caigut… bastant estrany, potser duia un parell de dies així. He aconseguit fer un ssh i això és el que n’ha sortit:
markus@myth:~$ top

Impressionant! Quasi 4000 processos, la cpu tranquil·la i el system load pels núvols... Després d'un ps aux normal he tret aquest:
markus@myth:~$ ps aux | grep exim4 | wc -l
3857
Putu exim! A la bassa…
markus@myth:~$ sudo killall -9 exim4
Password:
markus@myth:~$ ps aux | grep exim4 | wc -l
1
Ara que està tranquil mirem que pot haver passat:
markus@myth:~$ less /var/log/exim4/mainlog

uH?? Que fa la cosa aquesta enviat a través de google al compte markus@kusw3.com. Sembla que l’error està per aquí… Ara tot torna a la normalitat.

Reboot de l’apache que havia quedat KO, per això no servia les meves webs.
