What version of FreeBSD and BIND are you running? What is the configuration of your machine -- CPU(s), memory, and network cards certainly. Have you compiled a custom kernel for the machine; if so include the kernel config file you're using. If not, the problem is simple to diagnose: you need more network buffer space to handle the load. The simplest way to do this is to increase the "maxusers" figure in the configuration until the problem stops. If you're running the 3.2-RELEASE generic kernel, raise maxusers to 64 and try again. Please, post more information so we can help you. We don't want you to (and us by reference) to get embarrased on this. ;^) -- "Where am I, and what am I doing in this handbasket?"
