Description
Non-important issue at all, just logging so it can be added to filters. Extremely sporadic. Expect run times of 1h+ even with 200 threads repeating the SQL. Only one of the CHECKSUM TABLE statements is required, they can all fail with the given assertion.
SET @@max_statement_time=0.0001; |
CHECKSUM TABLE performance_schema.rwlock_instances; |
CHECKSUM TABLE performance_schema.table_io_waits_summary_by_table; |
CHECKSUM TABLE performance_schema.users; |
Leads to:
