netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory

While debugging some custom scripts, I found that 3 of my boxes have
large hobbitclient.log files.

They contain the same messages:

netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory netstat: sysctl: net.inet.tcp.stats: Cannot allocate memory

All three boxen are FreeBSD 5.4-STABLE.

All three are 4.1.2p1.

Do I need to enable this in sysctl.conf?

Thanks,
