hi guys i got a crash and aria engine don't startup, any help? 161222 03:41:13 mysqld_safe Starting mysqld daemon with databases from /home/mysql/data/local/ 2016-12-22 3:41:13 139878188566400 [Warning] 'THREAD_CONCURRENCY' is deprecated and will be removed in a future release. 2016-12-22 3:41:13 139878188566400 [Note] /usr/mariadb/mariadb/bin//mysqld (mysqld 10.1.5-MariaDB-log) starting as process 19217 ... 2016-12-22 3:41:13 139878188566400 [Note] mysqld: Aria engine: starting recovery recovered pages: 0% 3082852397% 0%161222 3:41:13 [ERROR] 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. To report this bug, see http://kb.askmonty.org/en/reporting-bugs 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. Server version: 10.1.5-MariaDB-log key_buffer_size=629145600 read_buffer_size=4194304 max_used_connections=0 max_threads=52 thread_count=0 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1041422 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.
