SQL server gone away, on localhost test install

Installed in localhost to test, before considering on prd system.

Installed tinyIDS in normal way, enabled module, saved, and... got this (site dead). I wonder if it's a timeout and if tinyIDS makes the site that bit slower so I'd need to adjust a mySQL variable perhaps? Or maybe something worse... any thoughts?

Logged this as support request rather than error, as error is SQL server gone away, which maybe means the module caused a timeout issue? Error is:

Additional uncaught exception thrown while handling exception.
