Syslog e kern.log saturano la root

[Maurizio]

Salve a tutti, qualche giorno fa volendo vedere una risonanza magnetica con un programma di nome Alizams il mio PC un vecchio i5 di seconda generazione con 8 giga di ram si è piantato presumo perchè le immagini dicom erano troppe, poco dopo mi sono accorto che il pc non rispondeva bene e per un po non partiva proprio, mi è poi comparso un messaggio di spazio esaurito, allora sono andato nella cartella /var/log dove ho potuto constatare che i due log superavano i 3 giga ciascuno saturandomi così la partizione root, facendo una ricerca ho trovato un comando per azzerare i suddetti log sudo tee /var/log/syslog /dev/zero . Dopo diversi giorni oggi il problema si è ripresentato senza che io facessi nulla di pesante. Mi chiedevo e vi chiedo se si può evitare che il problema si ripresenti qual'ora sia possibile. Vi ringrazio anticipatamente per l'eventuale risposta e vi auguro buon anno anche se tardivamente.
