[Tekkit Legends, Multicraft status problem]

Buying more RAMs won't fix a multicraft problem, as the server works fine and it only needs 4GB RAMs at least
I think this is not the right place to ask about this issue

anyway thanks, I guess... :\

[Tekkit Legends, Multicraft status problem]

Hi,
I tried to setup my server in multicraft and sadly, I couldn't figure a way to fix this annoying problem
this problem isn't about the setting of the modpack, everything is just fine it's all about multicraft and how it gets that the server is actually up
it gets stuck for some reasons in loading mode which disable the chat but the console works fine
here's the logs

to save your time from reading it the server is fine, but it won't show up in multicraft for some reasons that I don't know
the modpack isn't the problem as it seems, and cauldron.jar and kcauldron.jar had the same problem too, it seems like it only happen with 1.7.10 mc as I made a B-Team server already and it works fine
I know what happen with cauldron, but it doesn't explain why multicraft is stuck in loading mode.
I have few things I haven't tried which it's the conf file in multicraft jar
as I have no idea where to get it and how to set it up as I haven't tried it before
so any ideas?
