The error is telling you that the server doesn't have as much dedicated RAM as it would like. Consider adding more RAM in your .bat.

As for people not being able to connect, that's an entirely different matter.

Can anyone log into the server? If yes then get them to type /remove items -1 and see how many entities it removes. if it's a lot you have an item leak and your server is struggling to track all the items laying on the floor.

What the error means is the server, which is meant to run at 20 ticks per second is nowhere close to that. In tekkit the most common issues are probably a BC pipe leaking or a poorly set up cobblestone generator leaving a ton of items on the floor or an IC2 power loop.
