We are running an extremely large instance of mysql version 3.23.46 on Solaris 2.8. We are attempting to use a software version compiled 64 bit and have been experiencing memory related server crashes.
The behavior suggests that we are still unable to use more than 4G of memory. If the server is started with the following settings: key_buffer=4608M max_allowed_packet=1M table_cache=1024 record_buffer=1M sort_buffer=1M thread_cache=12 thread_concurrency=12 myisam_sort_buffer_size=512M We observe the following symptoms / problems: (1) A "mysqladmin variables" call shows that the key_buffer is set to be 1 G, not 4.5G. (2) Under any sort of database load, the server crashes with the following error output: mysql got signal 10; 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=4831834112 record_buffer=1044480 sort_buffer=1048568 max_used_connections=0 max_connections=512 threads_connected=1 It is possible that mysqld could use up to key_buffer_size + (record_buffer + sort_buffer)*max_connections = 5765112 K bytes of memory Hope that's okay, if not, decrease some variables in the equation. If the server is started with more modest settings (e.g., key_buffer_size=2G), mysql operates correctly. Additionally, "mysqladmin variables" shows a correct key_buffer value. System memory is not a constraint ( 6 G real memory and 14.5 G swap). --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
