MySQL 5.7 High Memory usage Killed by OOM

clickround
i upgrade my WHM server / Cent-OS 7 from MySQL 5.6 to 5.7 this server is dedicated server for whm server [apache, php, mysql] hosting for multi web sites with very small number of visitors. after that upgrade every few hours my server memory full by MySQL which after hours of MySQL restart it exceed 80% of whole memory. i increase my server ram from 13GB to 17.5GB and still get same problem also i create swap for 3GB and still same problem. i change in MySQL configuration without any luck. so if anyone can help with that. i try also mysqltuner but the problem that MySQL restarting every few hours and they said that MySQL must be running more than 24 hour at lease for recommendation to be accurate. this is the configuration of the etc/my.cnf file: [mysqld] default-storage-engine=INNODB innodb_file_per_table=1 max_allowed_packet=268435456 open_files_limit=80000 collation_server=utf8_unicode_ci character_set_server=utf8 slow_query_log=1 long_query_time=3 max_connections = 200 sort_buffer_size=16M join_buffer_size=1M innodb_sort_buffer_size=16M read_buffer_size=1M read_rnd_buffer_size=2M max_heap_table_size=64M tmp_table_size=64M key_buffer_size=128M #event_scheduler=on innodb_log_file_size=384M query_cache_type=0 query_cache_size=0 table_open_cache=78000 table_definition_cache=39400 innodb_buffer_pool_instances=3 innodb_buffer_pool_size=3G and the result of mysql tuner i don't know if it can help as MySQL not running from a long time: >> MySQLTuner 1.7.19 - Major Hayden >> Bug reports, feature requests, and downloads at http://mysqltuner.com/ >> Run with '--help' for additional options and output filtering [--] Skipped version check for MySQLTuner script [OK] Currently running supported MySQL version 5.7.31-log [OK] Operating on 64-bit architecture -------- Log file Recommendations ------------------------------------------------------------------ [OK] Log file /var/lib/mysql/bilal.hosting.err exists [--] Log file: /var/lib/mysql/bilal.hosting.err(38K) [OK] Log file /var/lib/mysql/bilal.hosting.err is readable.

Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1 We will suggest raising the 'join_buffer_size' until JOINs not using indexes are found. See https://dev.mysql.com/doc/internals/en/join-buffer-size.html (specially the conclusions at the bottom of the page). Increase table_open_cache gradually to avoid file descriptor limits Read this before increasing table_open_cache over 64: xxxxxxxxxxxxxxxxxxxx Read this before increasing for MariaDB https://mariadb.com/kb/en/library/optimizing-table_open_cache/ This is MyISAM only table_cache scalability problem, InnoDB not affected. See more details here: https://bugs.mysql.com/bug.php?id=49177 This bug already fixed in MySQL 5.7.9 and newer MySQL versions. Beware that open_files_limit (80000) variable should be greater than table_open_cache (39895) Variables to adjust: *** MySQL's maximum memory usage is dangerously high *** *** Add RAM before increasing MySQL buffer variables *** join_buffer_size (> 1.0M, or always use indexes with JOINs) table_open_cache (> 39895) table_definition_cache(39400) > 44053 or -1 (autosizing if supported) innodb_buffer_pool_size (>= 5.4G) if possible.
note i try to put innodb_buffer_pool_size to 6G as recommended but still the same memory load. in mysql tuner result they gave result that Maximum possible memory usage: 57.2G (336.45% of installed RAM) is that a problem and how to fix this issue! also no load on the server or mysql. and on top just the mysql is taking the memory above 70% of it and this the output of free: total used free shared buff/cache available Mem: 16G 13G 323M 14M 3.6G 3.6G Swap: 3.0G 2.1G 933M Total: 19G 15G 1.2G

    If you only have a few websites with only a few visitors then 10+GB of memory should be much more than enough. I would like into the process list to see what is causing this. You can do so from WHM under MySQL Processlist if I recall.

    yes i check mysql process list periodically using phpmyadmin and "mysqladmin processList" command but most of times empty. this is an example: mysqladmin processList +-------+-----------------+-----------+----+---------+------+-----------------------------+------------------+ | Id | User | Host | db | Command | Time | State | Info | +-------+-----------------+-----------+----+---------+------+-----------------------------+------------------+ | 1 | event_scheduler | localhost | | Daemon | 5496 | Waiting for next activation | | | 14944 | root | localhost | | Query | 0 | starting | show processlist | +-------+-----------------+-----------+----+---------+------+-----------------------------+------------------+

    It's similar when you are having high load as well? Looks like something else is causing the high load then.....

    Troubleshooting high load attributed to MySQL is best performed by a system administrator. If you don't have one you might find one here: System Administration Services

    yes even when there is high load there is no process in mysql. but mysql consumes above 80% of the memory when check top: PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 11690 cpanels+ 20 0 3091984 269868 828 S 0.3 1.5 32:10.95 java 27629 mysql 20 0 15.8g 14.5g 6528 S 0.3 85.6 81:37.12 mysqld 29470 root 20 0 246052 16328 588 S 0.3 0.1 0:14.03 spamd 29649 nobody 20 0 366968 80760 3380 S 0.3 0.5 0:00.53 httpd 1 root 20 0 194108 4844 2476 S 0.0 0.0 12:49.30 systemd
