Everytime I run up to someone I crash?

[Snicklefrittz]

I noticed it just today (I havent been on actively in a while so this could be from a patch) but everytime I run up to someone in combat my client locks up. I am not sure if I am going LD or what. I can run through EC tunnel fine without lag, but if someone is fighting a fire beetle in EFP I have to steer clear of them because the second I get in about 5 feet of them I am locked up.

Any ideas?
