After moving the database from Linux 2.4 to FreeBSD 6.2, the mysqld crash very frequently! I think the problem is on FreeBSD when myusql is heaving loading. I have another same machine with lower loading, the mysql is stable. ===== 8< ================ Version: '5.0.37-log' socket: '/tmp/mysql2.sock' port: 3307 MySQL Community Server (GPL) 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=402653184 read_buffer_size=2093056 max_used_connections=69 max_connections=130 threads_connected=53 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_connections = 1191414 K bytes of memory Hope that's ok; if not, decrease some variables in the equation. ===== 8< ================ db1# limits Resource limits (current): cputime infinity secs filesize infinity kB datasize 2621440 kB stacksize 524288 kB coredumpsize infinity kB memoryuse infinity kB memorylocked infinity kB maxprocesses 5547 openfiles 11095 sbsize infinity bytes vmemoryuse infinity kB db1# ===== 8< ================ The configuration in my.cnf: [mysqld2] port = 3307 socket = /tmp/mysql2.sock character-set-server = utf8 datadir = /db/data2 max_connections = 130 interactive_timeout = 20 nice=-15 thread_concurrency = 8 skip-locking key_buffer = 256M max_allowed_packet = 1M table_cache = 400 sort_buffer_size = 4M read_buffer_size = 2M read_rnd_buffer_size = 4M myisam_sort_buffer_size = 64M thread_cache_size = 32 query_cache_size= 64M join_buffer_size = 4M server-id = 233 log-bin = mysql-bin skip-bdb innodb_data_home_dir = /db/data2/ innodb_data_file_path = ibdata1:2G:autoextend innodb_buffer_pool_size = 512M innodb_additional_mem_pool_size = 8M # Set .._log_file_size to 25 % of buffer pool size innodb_log_file_size = 64M innodb_log_buffer_size = 6M ##innodb_flush_log_at_trx_commit = 1 innodb_lock_wait_timeout = 30 replicate-ignore-table=friend.SendVKiss replicate-wild-ignore-table=friend.fc_% replicate-wild-ignore-table=friend._search_result_% ===== 8< ================ Last, the FreeBSD boot message: Copyright (c) 1992-2007 The FreeBSD Project.
