Re: MySQL server crash after running SELECT queries with a connection pool of 60

For starters, are the queries run through an app? If so, do they also crash the server when tun from the mysql client program or mysql shell?

Then, let's see the results of ...

- running Explain Analyze on the queries, esp. on the query that's running when the crash occurs

- running Show Engine InnoDB Status while the query is running over that connection pool

- the result of this calculation: innodb_buffer_pool_size + innodb_ft_total_cache_size + innodb_additional_mem_pool_size + innodb_log_buffer_size + query_cache_size + tmp_table_size + key_buffer_size + max_connections * ( thread_stack + max( max_allowed_packet, net_buffer_length ) + net_buffer_length + read_buffer_size + read_rnd_buffer_size + sort_buffer_size + join_buffer_size )

- how much RAM is available to MySQL

= whether the query induces swapping
