/var/log is 57GB?

Today, while I was working, I could not save file from IDE to server.

Then, discovered that my disk on the VPS with 80GB bootable disk was full

After a litle digging, found out that /var/log has the mnost of it!

[root@edge ~]# du -csh /var/log | grep total
57G total
[root@edge ~]#

Is this normal?

I need to do something immediately....

help....

Update 01

/var/log/virtualmin is 57GB [root@edge ~]# du -csh /var/log/virtualmin | grep total
57G total
[root@edge ~]#

Can I download and delete any/some of it?

Update 02

Found the culprit: 57G a1z.us_error_log

[root@edge virtualmin]# du -hs * | sort -rh | head -5
57G a1z.us_error_log
17M git.edge.a1z.us_access_log
2.0M a1z.us_access_log
788K preachword.com_access_log
520K a1z.us_access_log-20190929.gz
[root@edge virtualmin]#

Further digging confirms that /var/log/virtualmin has 57 GB!

is it some kind of an attack??

Howdy -- thanks for contacting us!

There's a few possible causes for something like that... what is the output of these commands:

head -1 /var/log/virtualmin/a1z.us_error_log
tail -100 head -1 /var/log/virtualmin/a1z.us_error_log
[root@edge virtualmin]# head -1 /var/log/virtualmin/a1z.us_error_log

It doesn't look like the logs are old, so it doesn't look like a log rotation issue.

It appears that most of the entries in that log are syntax errors and warnings related to this file:

/home/a1z/cgi-bin/servers/lib/Servers/Home.pm

That's not something we're familiar with, but you may need to look into who is hitting that file (or the related application), and ensure it's legitimate traffic. You may also be able to make some tweaks so that it generates less data that's being logged.

I'm also seeing some errors in the logs about MySQL errors. The error code there indicates that a disk or partition may be full. I suspect that's just a byproduct of the log issue from the above file though.

You could always delete the large log file, and then monitor what's going into it once it gets re-created.

Note that if you delete it, you would likely need to restart Apache in order to free up the space.

I will delete and restart apache.

Thanks.
