Hi there Busi,
I am part of the team that manage the well populated OZ.NZ Rawhope vanilla server. We run several management mods behind the scenes to help us keep our server running smooth and well managed.
Other than resetting the region files, like The Hated Crew mentioned above we use a great scripting mod created by djkrose to use for smaller "on the fly" jobs

This fantastic script gives you the ability to type this command into the console dj-regen Which Regenerates a chunk or custom area based on the world seed.
Usage:
1. dj-regen
2. dj-regen <x1> <z1> <x2> <z2>
3. dj-regen from
4. dj-regen to
1. Regenerates the chunk of the current player's position.
2. Regenerates all chunks of the given area, extended to chunk borders.
3. Saves the current player's position for usage 4.
4. Regenerates all chunks of the area from the saved position to current players position, extended to chunk borders.
We only do small regen's at a time, and ONLY when there is a small number (under 10) players online. Which is very rare on our server (unless ofcourse Tfp's announce a17 comming, then our numbers drop, lol) But be careful not to regen to much at a time, the large load plus many players online can be a heavy load and crash ya server, we have learn't to keep it to smaller jobs.
Each region is 32 chunks by 32 chunks, and each chunk is 16 blocks by 16 blocks, so we basically just fly over the area that needs fixing or regening, and type the command into the console and BAM, everything in the 16x16 block size is back to day one.
But for on-going large areas/towns/cities, we do have reset zones, infact all our towns are marked out as a reset zone, (helps to use Botman server manager to mark out those and maintain those0 then every 2 weeks Our server owner resets those town regions back to day one.
Your more than welcome to drop on by our server anytime, check out how we do things, but in saying that Botman also has a dedicated server set up with all the same mods we use on our server, for trying and testing for people like yourself.

The combination of the mods we use and the DJKrose script works perfectly together for maintaining our server. We have worked hard and closely with these mod creators to make our job of managing our server much easier for us and for others like yourself.
