We're running MySQL version 4.1.12 on Fedora Core 3 64-bit. we've been crashing; here is a mysqld.err file from one crash:
mysqld got signal 11; This could be because you hit a bug. It is also possible that this binary or one of the libraries it was linked against is corrupt, improperly built, or misconfigured. This error can also be caused by malfunctioning hardware. We will try our best to scrape up some info that will hopefully help diagnose the problem, but since we have already crashed, something is definitely wrong and this may fail. key_buffer_size=335544320 read_buffer_size=131072 max_used_connections=2049 max_connections=2048 threads_connected=371 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 4784112 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. 060108 14:43:07 InnoDB: Database was not shut down normally! InnoDB: Starting crash recovery. [InnoDB crash recovery elided] ----------------------------------------- We have 6G of memory on the server, and we checked -- we're not running out of memory. I'm guessing that mysqld crashed because of that 2049th connection -- shouldn't it just refuse the connection, not crash? The variables in the mysqld.err match the /etc/my.cnf: [mysqld] old-passwords tmpdir = /tmp/ datadir = /var/lib/mysql socket = /var/lib/mysql/mysql.sock port = 3306 key_buffer = 320M max_allowed_packet = 16M table_cache = 1024 thread_cache = 80 ft_min_word_len = 3 # Use this to prevent access via TCP/IP # skip_networking # Query Cache Settings - OFF due to overload of Session table query_cache_size = 32M query_cache_type = 2 # Log queries taking longer than "long_query_time" seconds long_query_time = 4 log-slow-queries = /var/lib/mysql/slow-queries.log log-error = /var/lib/mysql/mysqld.err # Try number of CPU's*2 for thread_concurrency thread_concurrency = 12 interactive_timeout = 28800 wait_timeout = 30 # when you change this recalculate total possible mysqld memory usage!! # key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections max_connections = 2048 max_connect_errors = 128 # Replication Master Server (default) # binary logging is required for replication log-bin server-id = 15 max_binlog_size = 2G # InnoDB tables innodb_data_home_dir = /var/lib/mysql/ innodb_data_file_path = ibdata1:3G;ibdata2:3G; innodb_log_group_home_dir = /var/lib/mysql/ innodb_log_arch_dir = /var/lib/mysql/ innodb_buffer_pool_size = 4G innodb_additional_mem_pool_size = 40M innodb_log_file_size = 160M innodb_log_buffer_size = 80M innodb_flush_log_at_trx_commit = 0 innodb_lock_wait_timeout = 50 innodb_thread_concurrency = 8 innodb_file_io_threads = 4 -------------------------------------------------------------------------------- Any help is appreciated. We've been crashing around the same time every day, our busiest time of day. -Sheeri -- MySQL General Mailing List For list archives: http://lists.mysql.com/mysql To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
