Perhpahs Already Running On That Port

I have an host and there an Minecraft server with an static IP adress and the default port,every time or like 80% I try to reload or restart the server from GameCP I cannot start the server because I get this error:

####### SERVICE START AT 2013-12-17 08:17 BY Brang #######

Loading libraries, please wait...

[08:18:01 WARN]: Perhaps a server is already running on that port?



I know the fix for local host server is to stop java from process...but what can I do if I am an a host like in this situation?1

PS:I can start the server at another port like 25566,but I don't wanna this,I wanna run the server on the default port.

 

when you have Root server reboot him! when not reboot your Computer!
