Yea Tony. Sadly you are right. I see lower peaks but after running server about 24 hours it starts building up again. Going from 3% processor use to steady 35% with peaks causing lag. I never had this problem with CraftBukkit 1.6.4 having about 25-35 players in game and 30 plugins. I use Windows Server 2008 R2 running in Solid State drive without any applications or background programs, Dedicated server 16GB RAM and A-6 3620 processor. Vanilla 1.7.2 and *.jar configuration -Xmx5120M nogui.
Deleting Mineshafts.dat works first but I found that updating Java from V.7 Update 7 (x64) to V.7 Update 45 (x64) really fixed problem. I have not deleted Minshafts.dat file today and I no longer get "Can't keep up" spam and no CPU peaks at all. Try this solution...
