Hello,
After reviewing the queries you provided, it seems that they are originating from the Joomla core, so there are no unexpected or unusual queries.
The issue you are experiencing could be due to a full disk on your server. Please ensure that you have enough free disk space to handle the queries and other operations.
Another possible cause could be the queries requiring excessive memory. Increasing the memory size for MySQL might be a solution. You can start by looking at parameters such as key_buffer_size, sort_buffer, read_buffer, and table_cache. Additionally, consider checking innodb_buffer_pool_size .
Hope this help.
