Hi, I upgraded our moderately loaded FreeBSD 7.0 amd64 recursors from 9.4.2-P1 to 9.4.3b2 to fix the open file descriptors issue. That certainly has helped in that respect with only half the number of open files (down to 4-500), and a 60-70% decrease in CPU time. Nice! However, I am now getting the following error: Jul 23 16:16:47 ns3t4 named[48325]: socket.c:4245: unexpected error: Jul 23 16:16:47 ns3t4 named[48325]: 48/Address already in use A quick look at the code shows that this is the error handling code, but I didn't get a hint from where it was called. Any hints are appreciated. Cheers, -erwin -- Erwin Lansing http://droso.org erwin@FreeBSD.org You are now free to move around the cabin erwin@aauug.dk
