What is the maximum number of players on a Minecraft/Bukkit server?

Does anybody have any experience with this? I'm having trouble finding the number.

Solution 1:

The only existing cap is the maximum integer size in java, which is 2^31-1 (2147483647).

Solution 2:

The number is set from the server.properties file and can be as large as you like as long as the server has enough bandwidth and memory to hold all the people.

If you're asking about a particular server, the maximum number of connections can be seen from the server list in game.

Solution 3:

There is no cap. 32-bit Java simply crashes after 2,147,483,647. If you had 64 bit Java you could probably go up to 9,223,372,036,854,775,807 but 32 bit clients that try to join your server might crash.
