Tamaño de syslog en constante aumento} ¿Por qué tengo (tengo) un tamaño muy grande de /var/log?

Question

Estoy en Ubuntu 18.04

Constantemente recibía Filesystem.root not enough spaceadvertencias. Entonces, busqué un poco en la web y aprendí cómo inspeccionar el uso del disco mediante,

sudo baobab

Luego vi que /var/logeran 74 GB y me sorprendí. Miré dentro de ese directorio y vi sys.logque había casi 72 GB.

Resolví el problema vaciando el contenido de ese syslogdocumento siguiendo la soluciónaquí.

Por ahora parece que está solucionado, sin embargoMe pregunto cuál podría haber sido el motivo de un archivo de registro tan grande. ¿Es eso habitual?

Gracias.

ACTUALIZAR

Ahora descubrí que no he solucionado nada, simplemente se llenó nuevamente hasta 30 GB en minutos, así que supongo que algo anda mal.

Yo inspeccioné syslogpor

cat syslog | more

AHORA, parece que recibo infinitos errores en segundos y eso llena el syslogdocumento. Sin embargo, soy incapaz de localizar cuál es el problema y cómo debo corregirlo.

Gracias.
