Hi Roberto,

according to this trace server crashed while evicting an object from table
cache (happens when we run out of table_open_cache). Likely because per-share
free tables list was broken. The rest is quite moot yet: e.g. it may (or may
not) also involve table definition cache eviction.

Will you report a bug or should I? A valuable information would be if this load
involved DDL and admin statements at least. table_open_cache and
table_definition_cache values, number of active connections, number of tables
participating in this load.

Thanks,
Sergey
