To play devils advocate here; vmalloc is a memory allocation call, if 
nf_conntrack (netfilter connection tracker) is using up more memory than 
usual maybe this machine is getting hammered by someone. Internet facing 
machine? Seeing high traffic packet wise? port wise?

Complete WAG here as I have no idea how nf_conntrack works or in fact 
what it really does.
