What are your server specs?
-Xmx MB 1280
-Xms MB 1280

Recommended is 4GB minimum for both servers and clients.

1280MB is not enough

Are you using minecraft hosting provider or a dedicated/local server not designed for minecraft?
(just giving the OS version isn't enough information - where is it located, is it a dedicated or shared - vps/vm?)
