    This is on a CentOS Cacti server that has ran for months on end with no problem.

    Now even for snmpwalk -v1 -cpublic localhost .1 results starts streaming through and halfway through results stop being listed for a moment and I get Timeout: No Response from localhost.

    Happens with other hosts that I could successfully query for months. What could this be?

    That largely depends on how you configure your router / what your router is running.

    You can e.g. create virtual eth interfaces in linux (eth0, eth0:1, etc.)

    auto eth0:1
iface eth0:1 inet static
address [ip]
netmask [netmask]

    Then specify and bind the snmpd address in the snmpd configuration

    OPTIONS="-Lsd -Lf /dev/null -p /var/run/snmpd.pid -a -x 127.0.0.1 [ip]"

    You can also simply specify udp: to listen on all interfaces. I.e.

    OPTIONS="-Lsd -Lf /dev/null -p /var/run/snmpd.pid -a -x udp: "
