mysqlの実行中に以下のエラーが発生します。
2018-08-30 06:17:41 0x7f35db7fe700 InnoDB: Assertion failure in thread 139869292586752 in file btr0cur.cc line 352 InnoDB: Failing assertion: btr_page_get_prev(get_block->frame, mtr) == page_get_page_no(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/5.7/en/forcing-innodb-recovery.html InnoDB: about forcing recovery. 06:17:41 UTC - 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. Attempting to collect some information that could help diagnose the problem. As this is a crash and something is definitely wrong, the information collection process might fail. key_buffer_size=268435456 read_buffer_size=131072 max_used_connections=1 max_threads=64 thread_count=1 connection_count=1 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 287576 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.

こちらの解消方法をご存知の方いらっしゃいますでしょうか。
他にも情報が必要であればお伝えします。
補足要求。1.このエラーは継続して発生しますか? 2.update中とのことですが、autocommitしていましたか?そうでなければ、何件ぐらいupdateしたときに発生しましたか? 3.メモリの使用状況を確認してください。mysql実行状況に対して、メモリは十分足りてますか? 4.エラーメッセージに書かれている内容は読み取れますか?
補足要求を書いたばかりですが情報連携です。 https://bugs.launchpad.net/percona-server/+bug/1428331 上記の記事とエラー発生場所が同一なので、どうやらInnoDBのバグの模様。ご愁傷様です。。。 もし継続してエラーが発生するようなら、エラーメッセージ中にリカバリー方法が記載されたURLが書いてありますので、そちらを参考に復旧されてみてはどうでしょうか。
