[LinuxLudus] Crash frequenti

[Valerio Pachera]

Ho firefox che va spesso in crash su un laptop.
Va in crash sia che usi firefox-esr pacchettizzato da debian, che firefox
quantum scaricato da tar.gz.
Poco fa ho ricevuto die messaggi in console di questo tipo:

Firefox è il programma che occupa più ram, senza dubbio.
Dico questo perché sospetto di avere problemi con la ram ed è più probabile
che sia firefox ad andare in crash.
Quando sono apparsi i messaggi mapcount:-1 mapping firefox NON è andato in
crash, ma qualcos'altro si.

Non molto tempo fa avevo fatto un memory test e non aveva trovato problemi.

Cosa ne pensate?
