nuBuilder Forum

I noticed that the /var/log/mysql/mysql.log file is growing rapidly & I've had to delete the /var/log/mysql/*gz files several times and restart mysql

When I first discovered this, /var/log/mysql/mysql.log was 3gb+

so I did the following command to monitor what & when the file is getting written to...
tail -f /var/log/mysql/mysql.log

after I login to nubuilder, I get a series of queries (see below) on my console where the tail command is running... every second, another series of queries...even though I'm not doing anything in browser

rnott,
nuBuilder is an application that use a database to get, manage and store data; some queries are needed to start and configure the application, to check the login credentials, to create and delete temporary tables, etc: that's the normal workflow!
I think delete log files is not a good idea... That's the place where you have to look if something goes wrong.

What is the problem? Free disk space?
Run this command in your terminal to see what's the folder that takes up more space: Instead to delete log files I suggest to configure logrotate in your system.

Hope this helps,
Max
