Error 23 (hy000): Out Of Resources When Opening File (errcode: 24)
am If you get the following error while creating a backup:Error out of resources when opening file mysql while backing up database USER_NAME mysqldump error output: mysqldump: Error: 'Out of resources when opening file '/tmp/#sql_390d_2.MYD' mysql open_files_limit (Errcode: 24 - Too many open files)' when trying to dump tablespaces mysqldump: Couldn't execute 'show fields from `NAME_accesslog`': Out of resources when opening file '/tmp/#sql_390d_0.MYD' (Errcode: 24 - Too many open files) (23)150707 0:15:49 [ERROR]
Mariadb Open_files_limit
Error in accept: Too many open filescheck this forum thread for solutions: http://forum.directadmin.com/showthread.php?t=47098 Some solutions: 1) Edit /etc/init.d/mysqld and add this to the top, after #!/bin/shulimit -HSn 1024 ulimit -HSn 32768 ulimit -HSn 1024000which should force it to try and set it as high as it can go. If one of the value is too high, delete that line, or lower the value. 2) Check /etc/my.cnf. Under the [mysqld] section, if you have a open_files_limit variable, increase it, eg:open_files_limit=32768then restart mysqld. 3) Confirm in mysql itself by checking the open_files_limit variable to ensure it's increased, by running the SQL query:show global variables like 'open%';
Hayden 14 Comments While running into out of resources when opening file myd MySQL's open files limit will manifest itself into various mariadb out of resources when opening file error messages, this is the standard one that you'll receive during a mysqldump:

First, if you find that you only hit the limit during mysqldumps and never during normal database operation, just add --single-transaction to your mysqldump command line options. This will cause mysql to keep only one table open at a time. However, if this happens while backups aren't running, you may want to increase the open_files_limit in your MySQL configuration file. By default, the variable is set to 1,024 open files. For further reading: 5.2.3.
