Re: [Bug 1434758] Re: mysqld: errno: 24 - Too many open files
Hi Robie, The internal assessment here is that most appropriate solution would be the one you have mentioned as the last option. It would be easier if user owns the responsibility for creating and managing the MySQL service file under /etc with following settings or more as needed: [Service] LimitNOFILE=x LimitMEMLOCK=x This will help in avoiding any conflict between user settings and package settings. We may add a comment to explain this to the users. Please let me know if you need more information.

See https://lists.ubuntu.com/archives/ubuntu- devel/2010-September/031446.html for details. If someone from upstream can confirm definitely that MySQL definitely does handle higher number file descriptors correctly though, then I have no objection. I understand though that users do want to be able to tune the value. So, what else can we do? It seems to me that now that we're using systemd there are two different places where the setting can be made - from my.cnf, or from the systemd service definition - whereas previously users tended to do it in just my.cnf. Having it set in two places is confusing. my.cnf cannot raise beyond the systemd setting, but we cannot make the systemd setting infinity because of the security concern above. So given that I don't want to change systemd's default to infinity, I think it makes sense to expect users to change the systemd service definition (copy /lib/systemd/system/mysql.service to /etc/systemd/system/ and set LimitNOFILE etc there) if they want to change the default value, and to not set open_files_limit in my.cnf at all. If this is reasonable, then this bug is Invalid. Is it reasonable?
