It's syslog-ng or another logger that creates this file. Check /etc/syslog-ng/syslog-ng.conf if you're using syslog-ng.
Obviously something is going wrong if it gets that big. |

its probably your kernel log file. you should read the file and fix the problem. maybe you have some debugging options compiled into your kernel or into some modules, what makes the output that huge?
so read the logfile, and look for the probably continously appearing error.

so obviously has something to do with to do with usb-storage module, but I probably have some stupid debugging option compiled into my kernel.... i will need to take a look.... I already thought i might have to recompile my kernel and i think i removed all options that could be related.... but i will take another look....
is there an equivalent of usb-storage for firewire? I am moving to firewire soon anyway....

got it, but the reason for the logfile are IMHO your debug options for usb. to rotate and compress logfiles, logrotate could be the weapon of choice. if your cron job didn't work properly the file is maybe not > 500MB a day 
have you setup your crond properly? there are cronds which has to be merried with cron.daily, cron.hourly and so on.

yeah i know otherwise i wouldnt have mentioned it, but I know for a fact that it does generate at least 64MB per day, I first noticed it when it was 16GB big!!!!!! | Quote: | | there are cronds which has to be merried with cron.daily, cron.hourly and so on. |
what is merried? I just moved cron daemons actually, from vixie-cron to fcron all my other cron jobs work! but I had fcron before July 3rd so I know something as screwed up that particular cron job since then
my cron job is just | Code: | #!/bin/sh
rm -f /var/log/kern.log |

Sorry, I mistyped married... 
you have to perform | Code: | | crontab /etc/crontab |
in order to activate the cron.hourly, cron.daily ...
there is also the fine cron guide http://www.gentoo.org/doc/en/cron-guide.xml here
