If you're using pagination, you should only be pulling a very tiny fraction of that. Chances are you're trying to select far too many records, causing the script and/or your MySQL DB to time out, hence the connection error upon reload.
A blank white page usually means an error, try adding error_reporting(E_ALL) to your controller to see if a more specific error pops up.
And post the code for your query and pagination, because I bet it's not adding a limit/offset properly.
And you don't need multiple threads about the same problem...
