Try password1 If that doesn't work, use Hamachi. And make sure you run the SERVER .jar with hamachi if that doesn't work.

What version do you use? Dev or Rec?

I may be able to fix it, but I need a log. I've handled enough errors for me to fix this.

Oops messed up my words there. And either way it would work. When It comes to Ram/Bit I know what i'm talking about.

I see the problem. Your launcher build is out of date. Get the newer one at http://www.technicpack.net/technic/

Wrong spot.

Tekkit is only for Multiplayer. Technic is Singleplayer. With no Error message or Log, just delete your .techniclauncher and re-download it.

Are you using a Dev build of Tekkit? That may be the problem.

.techniclauncher>logs>(Find the highest number log)

It must be a 64-bit server. I have troubles with those kind of Server's.

It may be Thaumcraft 2 (With the mass crystal spawning)

It may be a bug with the Crystal chest. Since Crystal CHests let you see the items outside, it CAN Bug at anytime.

Is the server 64-bit? because I got the same error last time and I changed my server to 32-bit to stop lag issues. Just find the .bat file "launch" and open it with any Editing software by right-clicking and press edit. After that change all the numbers you see to 1 and it should cause no lag in your server.

Error message? Log? Whenever I don't see those things I would just tell you to delete your .techniclauncher and re-download it.

I say this to all Hamachi users- Use Hamachi for a LAST RESORT. Try to port forward your server first. Plus i think your not even running your server -.- You need to use Minecraft server jar and Hamachi to make a server. (You would know this if you really no what hamachi is for.)
