... and on and on.
Syslog is more than 400MB and kern.log is more than 500MB. This is in about 3h of laptop usage.
The system is a Dell Latitude D630. I am using Debian Squeeze with kernel 2.6.26-2-amd64.
After a long time on, when I try to open a file from the Internet,
Iceweasel says there is not enough room in tmp to store the file.
I can see regular activity in the hard drive, in the system monitor, which I'm sure is log writing.
Thank you,
António
