Ubuntu: large syslog and kern.log files -

-

logging ubuntu machine, warning running out of disk space. tracing back, find syslogs, kern.log(s) eating 1tb disk. 

-rw-r----- 1 syslog adm 240g feb 25 14:22 kern.log -rw-r----- 1 syslog adm 516g feb 21 07:59 kern.log.1 -rw-r----- 1 syslog adm 1.1k feb 15 07:39 kern.log.2.gz -rw-r----- 1 syslog adm  19k feb  7 07:56 kern.log.3.gz -rw-r----- 1 syslog adm  37k feb  1 07:45 kern.log.4.gz -rw-r----- 1 syslog adm  23g feb 25 14:52 syslog -rw-r----- 1 syslog adm  25g feb 25 08:11 syslog.1 -rw-r----- 1 syslog adm 1.6g feb 24 07:49 syslog.2.gz -rw-r----- 1 syslog adm 1.7g feb 23 08:18 syslog.3.gz -rw-r----- 1 syslog adm 3.4g feb 22 08:19 syslog.4.gz -rw-r----- 1 syslog adm 3.6g feb 21 07:59 syslog.5.gz -rw-r----- 1 syslog adm 6.9g feb 20 07:38 syslog.6.gz -rw-r----- 1 syslog adm 7.3g feb 19 07:36 syslog.7.gz

from snippet above, can find kern.log , kern.log.1 eating 80% of 1tb disk. can space deleting files, think won't solve problem.

does have idea on issue might be? saw can logging level by:

cat /proc/sys/kernel/printk

and get

4    4    1    7

have checked content of files? there's going on server causing events generated. resolve whatever issue causing that, , logs should return normal size.

i use winscp download , edit .scss files , sass on linux (on server) compile them .css . after saving file, use: sass scss/style.scss css/style.css , replaces css file compiled sccs. the problem i want skip part return command line after editing scss file, sake of automation , saving time. but, if use watch command: sass --watch scss/style.scss:css/style.css synchronize 2 files, alerts nonexistent css errors pop up: change detected to: scss/style.scss error scss/style.scss (line 232: invalid css after "...ht: bold; line-": expected "{", "") note that when file uploads quicker usual (sometimes happens) watch command job, no errors. this because, when file upload takes time, sass compiles scss file (on server) before uploaded remote folder. thus, compiles part of file, resulting in css errors. is there way set timer watch command waits few seconds after detects changes , before compiling? any other way overcome is, of course, ...
