my.cnf # Example MySQL config file for medium systems. # # This is for a system with little memory (32M - 64M) where MySQL plays # an important part, or systems up to 128M where MySQL is used together with # other programs (such as a web server) # # MySQL programs look for option files in a set of # locations which depend on the deployment platform. # You can copy this option file to one of those # locations. For information about these locations, see: # http://dev.mysql.com/doc/mysql/en/option-files.html # # In this file, you can use all long options that a program supports. # If you want to know which options a program supports, run the program # with the "--help" option. # The following options will be passed to all MySQL clients [client] #password = your_password port = 3306 socket = /tmp/mysql.sock # Here follows entries for some specific programs # The MySQL server [mysqld] port = 3306 socket = /tmp/mysql.sock # skip-locking key_buffer_size = 32M max_allowed_packet = 1M table_open_cache = 512 sort_buffer_size = 64M join_buffer_size = 64M net_buffer_length = 8K read_buffer_size = 256K read_rnd_buffer_size = 512K myisam_sort_buffer_size = 512M tmp_table_size = 512M max_heap_table_size = 64M thread_cache_size = 200 table_lock_wait_timeout = 500 myisam_max_sort_file_size = 10G max_connections = 2000 wait_timeout = 7200 query_cache_size = 16M slow_query_log_file=/usr/local/mysql/slowquery.log long_query_time=2 character-set-server=utf8 ndbcluster ndb-connectstring=192.168.100.23 default-storage-engine=ndbcluster skip-name-resolve [mysql_cluster] ndb-connectstring=192.168.100.23 # Don't listen on a TCP/IP port at all.

However, in case you choose this method, then # start replication for the first time (even unsuccessfully, for example # if you mistyped the password in master-password and the slave fails to # connect), the slave will create a master.info file, and any later # change in this file to the variables' values below will be ignored and # overridden by the content of the master.info file, unless you shutdown # the slave server, delete master.info and restart the slaver server. # For that reason, you may want to leave the lines below untouched # (commented) and instead use CHANGE MASTER TO (see above) # # required unique id between 2 and 2^32 - 1 # (and different from the master) # defaults to 2 if master-host is set # but will not function as a slave if omitted #server-id = 2 # # The replication master for this slave - required #master-host = <hostname> # # The username the slave will use for authentication when connecting # to the master - required #master-user = <username> # # The password the slave will authenticate with when connecting to # the master - required #master-password = <password> # # The port the master is listening on. # optional - defaults to 3306 #master-port = <port> # # binary logging - not required for slaves, but recommended # log-bin=mysql-bin # Uncomment the following if you are using InnoDB tables innodb_data_home_dir = /usr/local/mysql/data #innodb_data_file_path = ibdata1:10M:autoextend #innodb_log_group_home_dir = /usr/local/mysql/data # You can set .._buffer_pool_size up to 50 - 80 % # of RAM but beware of setting memory usage too high innodb_buffer_pool_size = 1024M innodb_additional_mem_pool_size = 20M # Set .._log_file_size to 25 % of buffer pool size innodb_log_file_size = 5M innodb_log_buffer_size = 8M #innodb_flush_log_at_trx_commit = 1 innodb_lock_wait_timeout = 50 [mysqldump] quick max_allowed_packet = 16M [mysql] no-auto-rehash # Remove the next comment character if you are not familiar with SQL #safe-updates [myisamchk] key_buffer_size = 20M sort_buffer_size = 20M read_buffer = 2M write_buffer = 2M [mysqlhotcopy] interactive-timeout explain '1', 'PRIMARY', 'c', 'ref', 'file_type', 'file_type', '63', 'const', '7', 'Using where' '2', 'SUBQUERY', 'c', 'const', 'PRIMARY', 'PRIMARY', '4', '', '1', ''

well, since the crash is in the query cache, any select could cause it. to prevent a crash, put into my.ini: query_cache_size=0 query_cache_type=0 there were similar bugs reported in the passed, need to find them.
