Public bug reported: V: 5.7.20-0ubuntu0.16.04.1
I think it was when I added a field to a table (via phpMyAdmin). 2017-11-02 09:36:47 0x7fdc38ff9700 InnoDB: Assertion failure in thread 140583825807104 in file pars0pars.cc line 822 InnoDB: Failing assertion: sym_node->table != NULL 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. 08:36:47 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=16777216 read_buffer_size=131072 max_used_connections=40 max_threads=151 thread_count=8 connection_count=8 It is possible that mysqld could use up to key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 76385 K bytes of memory Hope that's ok; if not, decrease some variables in the equation.
