View Full Version : [ubuntu] Massive syslog and other files

January 31st, 2010, 01:06 PM
Hi. All I ever use my ubuntu for is programming C, and now I cant even do that because I dont have enough room. I looked around and these are the four files in my var/log folder that are causing me to have no space :/

kern.log - 5GB
messages - 1.9GB
syslog - 2.9GB
syslog.1 - 1.3GB

Can I delete these? And is there a fix for them doing whatever this is?

Thanks in advance.

Seeing a "syslog.1" means your logs probably *did* get rotated, however log file sizes could be due to excessive errors or way verbose logging or unusual log rotation settings. For checking your log rotation see /etc/logrotate.conf and /etc/logrotate.d and /etc/cron.daily/sysklogd.
* If your machine is not always on you might benefit from running anacron or equivalent.
** If you don't read system logs then I suggest you install Logwatch. Way easier to read the emailed reports and adjust whatever it alerts about.
*** Yes, you may be miffed by syslog and such but bumping this fast is not polite.

Aaron, a few users have reported such problems (http://ubuntuforums.org/showthread.php?t=1331883&highlight=syslog+space)
Specifically, syslog, syslog.1 and user.log are taking up 309GB of space altogether but these are entries relating to Pulse Audio and a couple of other applications.

What is filling your logs?

You can simply delete those log files. You can also stop the syslog daemon, so they won't come back. Logging everything is usually a good idea, but on a development system in a R&D environment, it has little to no value.
