Dear list, So as we have a huge koha database with 7 million records on Koha 17.11.05 we always have such problem : during the day we noticed that koha began work slowly especially searching, we couldn't export data at that time and executed reports. We use MariaDB latest version and when execute this command "show status like Conn" we noticed that connections are very huge nearly 150 000.(See attached file)After restarted MariaDB the connections became 100. We,of course use documentation and added # key_buffer = 2000M max_allowed_packet = 16M thread_stack = 128K thread_cache_size = 8 # This replaces the startup script and checks MyISAM tables if needed # the first time they are touched myisam-recover = BACKUP max_connections = 500 max_user_connections = 500 #table_cache = 64 thread_concurrency = 300 table_cache = 30000 open_files_limit = 65000# # * Query Cache Configuration # query_cache_limit = 50M query_cache_size = 300M # * InnoDB # # InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/. # Read the manual for more InnoDB related options. There are many! # You might want to disable InnoDB to shrink the mysqld process by circa 100MB. #skip-innodb innodb_buffer_pool_size=16777216 innodb_file_per_table We understand that it is opac search results which didn't reconnect after any search. Any suggestions? Thanks, Araik --- Это сообщение было проверено AVG на наличие вирусов. http://www.avg.com
