"long_query_time=5" is low when you talk about 5 seconds as i remember in previuos posts - given that a reasonable server should be able to handle hunredts to thousands of requests per second anything above 1 second is a alert sign
I restarted the mysql server (/etc/init.d/mysql restart on ubuntu) and tested the email page one again. I again see that error message on the browser, however, the log files are empty.
look also in phpinfo() for mysqlnd and mysql params containing "timeout" and/or "max"
