Maximum ARP Entries

Does anyone know if there is a maximum number of ARP entries/ 
adjacencies that FBSD can handle before recycling? 
I want to route several thousand ips direct to some interfaces so it 
will have 3-4k ARP entries..  I'm curious because in Linux I have to set
the sysctl net.ipv4.neigh threshholds a lot higher or it bombs with 'too 
many neighbors'...  I don't see a setting like this in BSD sysctl .
