InnoDB: End of page dump

InnoDB: Page may be an update undo log page

InnoDB: Database page corruption on disk or a failed

InnoDB: file read of page 380.

InnoDB: You may have to recover from a backup.

InnoDB: It is also possible that your operating

InnoDB: system has corrupted its own file cache

InnoDB: and rebooting your computer removes the

InnoDB: error.

InnoDB: If the corrupt page is an index page

InnoDB: you can also try to fix the corruption

InnoDB: by dumping, dropping, and reimporting

InnoDB: the corrupt table. You can use CHECK

InnoDB: TABLE to scan your table for corruption.

InnoDB: See also http://dev.mysql.com/doc/refman/5.6/en/forcing-innodb-recovery.html

InnoDB: about forcing recovery.

InnoDB: Ending processing because of a corrupt database page.

InnoDB: We intentionally generate a memory trap.

InnoDB: Submit a detailed bug report to http://bugs.mysql.com.

InnoDB: If you get repeated assertion failures or crashes, even

InnoDB: immediately after the mysqld startup, there may be

InnoDB: corruption in the InnoDB tablespace. Please refer to

InnoDB: http://dev.mysql.com/doc/refman/5.6/en/forcing-innodb-recovery.html

InnoDB: about forcing recovery.

160308 8:14:27 [ERROR] mysqld got signal 6 ;

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: 10.0.23-MariaDB-0+deb8u1

key_buffer_size=16777216

read_buffer_size=131072

max_used_connections=0

max_threads=153

thread_count=0

It is possible that mysqld could use up to

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 352315 K bytes of memory

Hope that's ok; if not, decrease some variables in the equation.



Thread pointer: 0x0x0

Attempting backtrace. You can use the following information to find out

where mysqld died. If you see no messages after this, something went

terribly wrong...

The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains

information that should help you find out what is causing the crash.

Any ideas?
