Neighbour table overflow

I am getting neighbour table overflow errors in my /var/log/message file.  It keeps popping up over and over.
BIND 9.1.0 keeps restarting and sending errors to the end-user that  there is not enough free space. All my partitions have more then 50% free space.

Thanks in advance for your help.

What's the exact error in the log, and what's the exact error the client sees?  What is the client doing that triggers the error?

Have you done a Google search on the exact error string?

Are you running any firewall rules that would prohibit this traffic?

Is the system running out of memory?  How much is free when this happens?
