Lets say that you spawned like thousnads of TNT and detonated it all at the same time. The explosion was so huge that it sends TNT across the map! And after maybe 20 seconds of just hovering in midair in a huge wave of lag, te server turns off and you are kicked off. WHAT WILL YOU DO?

To save the world, simply download a bukkit plugin called TNT Sweep. This plugin targets all TNT that either has been set into semi-explosion form or just TNT that was placed and would soon explode from the blast of the TNT already launched. Link is below, not my plugin but I was amazed at how it just solved myproblem by simply installing it onto the server...
