Minecraft Hexxit Suddenly Extreme Lag [closed]

I have a extreme lag problem on my server.

It's a dedicated Server on my local machine with me and up to 4 other players on it. We use the Hexxit-Mod-Pack on 1.5.2. I give my Minecraft 1Gb Memory. Disabling the mods is no option, but without mods it works properly.

We build a small city, with a 'Meteor Shield' (think it's important, because I have less lag without it.) So i run around, placing 'Land Protection Tester'. After a while, I moved a little bit away from my village I have big lags. The left side explains itselfs, the right side is the server log. Normally I play on about 40 to 60 FPS. But as you see above it's 0 to a maximum of 4 FPS and it does not restabilize even if I wait about half an hour. Do you have any idea how o avoid it except unbuild the 'Meteor Shield'? By the way, the lag only affects ME, not the others.

Maybe any option I can change or a little configuration change?

EDIT: maybe important also: As i encountered the lag, I tried relog. So disconnect, Multiplayer, Connect, then MC crashed with this log:
