Hi, We're use mariadb 10.1.3 as a main database of our system. We migrated data from develpment server to product server a week ago. Below is our error case : MariaDB shutdown with signal 6 when some query executes. (insert or update...) The error log is below. ------------------------------------------------------------------------ ---------------------------------- ... 2016-07-18 9:44:14 139882584566528 [ERROR] InnoDB: Block in space_id 0 in file /data001/masvc01/ibdata1 encrypted. 2016-07-18 9:44:14 139882584566528 [ERROR] InnoDB: However key management plugin or used key_id 286 is not found or used encryption algorithm or method does not match. 2016-07-18 9:44:14 139882584566528 [ERROR] InnoDB: Marking tablespace as missing.

--------------------------------------------------- So we export data from mariadb and import to new table space. After migration, we shutdown mariadb and restart. but signal 11 occurred and db crash. Below is our error log. ------------------------------------------------------------------------ -------------------------- 2016-07-19 8:55:09 140556344748800 [Note] /engn001/masvc01/mysql/bin/mysqld: Normal shutdown 2016-07-19 8:55:09 140556344748800 [Note] Event Scheduler: Killing the scheduler thread, thread id 1 2016-07-19 8:55:09 140556344748800 [Note] Event Scheduler: Waiting for the scheduler thread to reply 2016-07-19 8:55:09 140556344748800 [Note] Event Scheduler: Stopped 2016-07-19 8:55:09 140556344748800 [Note] Event Scheduler: Purging the queue. 0 events 160719 8:55:09 server_audit: STOPPED 2016-07-19 8:55:09 140556627830528 [Note] InnoDB: FTS optimize thread exiting. 2016-07-19 8:55:09 140556344748800 [Note] InnoDB: Starting shutdown... 2016-07-19 8:55:09 140556648810240 [Warning] InnoDB: Dumping buffer pool(s) to /data001/masvc01/ib_buffer_pool 2016-07-19 8:55:10 140556648810240 [Warning] InnoDB: Buffer pool(s) dump completed at 160719 8:55:10 2016-07-19 8:55:15 140556344748800 [Note] InnoDB: Shutdown completed; log sequence number 399145649446 2016-07-19 8:55:15 140556344748800 [Note] /engn001/masvc01/mysql/bin/mysqld: Shutdown complete 160719 08:55:16 mysqld_safe mysqld from pid file /engn001/masvc01/mysql/mysqld.pid ended 160719 08:57:05 mysqld_safe Starting mysqld daemon with databases from /data001/masvc01 2016-07-19 8:57:05 140304014350176 [Note] /engn001/masvc01/mysql/bin/mysqld (mysqld 10.1.14-MariaDB) starting as process 2608 ... 2016-07-19 8:57:06 140304014350176 [Note] InnoDB: Using mutexes to ref count buffer pool pages 2016-07-19 8:57:06 140304014350176 [Note] InnoDB: The InnoDB memory heap is disabled 2016-07-19 8:57:06 140304014350176 [Note] InnoDB: Mutexes and rw_locks use GCC atomic builtins 2016-07-19 8:57:06 140304014350176 [Note] InnoDB: Memory barrier is not used 2016-07-19 8:57:06 140304014350176 [Note] InnoDB: Compressed tables use zlib 1.2.3 2016-07-19 8:57:06 140304014350176 [Note] InnoDB: Using Linux native AIO 2016-07-19 8:57:06 140304014350176 [Note] InnoDB: Using SSE crc32 instructions 2016-07-19 8:57:06 140304014350176 [Note] InnoDB: Initializing buffer pool, size = 24.0G 2016-07-19 8:57:08 140304014350176 [Note] InnoDB: Completed initialization of buffer pool 2016-07-19 8:57:10 140304014350176 [Note] InnoDB: Highest supported file format is Barracuda. 2016-07-19 8:57:13 140304014350176 [Note] InnoDB: 128 rollback segment(s) are active. 2016-07-19 8:57:13 140304014350176 [Note] InnoDB: Waiting for purge to start 2016-07-19 8:57:13 140304014350176 [Note] InnoDB: Percona XtraDB (http://www.percona.com http://www.percona.com/ ) 5.6.29-76.2 started; log sequence number 399145649446 2016-07-19 8:57:13 140273638147840 [Note] InnoDB: Dumping buffer pool(s) not yet started 2016-07-19 08:57:13 7f94005f8700 InnoDB: Loading buffer pool(s) from /data001/masvc01/ib_buffer_pool 2016-07-19 8:57:13 140304014350176 [Note] Plugin 'FEEDBACK' is disabled. 160719 8:57:13 server_audit: MariaDB Audit Plugin version 1.4.0 STARTED. 2016-07-19 8:57:13 140304014350176 [Note] Server socket created on IP: '::'. 2016-07-19 8:57:13 140304014350176 [Warning] 'user' entry 'root@lgedglap02v' ignored in --skip-name-resolve mode. 2016-07-19 8:57:13 140304014350176 [Warning] 'user' entry '@lgedglap02v' ignored in --skip-name-resolve mode. 2016-07-19 8:57:13 140304014350176 [Warning] 'proxies_priv' entry '@% root@lgedglap02v' ignored in --skip-name-resolve mode. 2016-07-19 8:57:13 140273595853568 [Note] Event Scheduler: scheduler thread started with id 1 2016-07-19 8:57:13 140304014350176 [Note] Reading of all Master_info entries succeded 2016-07-19 8:57:13 140304014350176 [Note] Added new Master_info '' to hash table 2016-07-19 8:57:13 140304014350176 [Note] /engn001/masvc01/mysql/bin/mysqld: ready for connections.

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 https://mariadb.com/kb/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.
