Hello,
I have a sugestion that i want to share. I would really enjoy if You switched your servers to 64-bit java. I know that this will be a lot of work but I have a reason why should you do that.
Servers on intense modpacks (Tekkit Legends ect.) offen require much more ram then 1.5GB (the maximum of 32-bit systems) And !.5 GB might be enough for a single player game but for a server it's too low. When I had my tekkit legends server I have expirienced a lot of problems with my server running out of memory when we were playing in 3 peopole. The server crashed randomly because of the low ram ammount (the world was new)(almoust after every crash the world was corrupted and unredable).
So.. I just recommend 3GB for servers like this...
