I made some minor changes to my nginx server using a Linux VPS running FreeBSD 10.3 with TLS, ciphers and then file caches. Except for the file caching, I had done these changes before without issue. I went away for the weekend and, when I came back, netstat -i showed Idrop as being 48665. The web sites on this server don't exhibit any problems that I can see.
I reverted all my changes back to their original but I still see the same value for Idrop and it never changes from day to day or throughout the day. All the other values change accordingly.
Notice that there are two web sites shown, both on different IPs. However, there are two other web sites on this same server with the same IP as website2 but they aren't listed. What's with that?
I have to say that, while I love networking, I never get to deal with it and this server has been around for several years, running without issues, so I'm at a loss as to how to troubleshoot this.

systemd-socket-proxyd
SYSTEMD-SOCKET-PROXYD(8) systemd-socket-proxyd SYSTEMD-SOCKET-PROXYD(8)NAME
systemd-socket-proxyd - Bidirectionally proxy local sockets to another (possibly remote) socket.
SYNOPSIS
systemd-socket-proxyd [OPTIONS...] HOST:PORT
systemd-socket-proxyd [OPTIONS...] UNIX-DOMAIN-SOCKET-PATH
DESCRIPTION
systemd-socket-proxyd is a generic socket-activated network socket forwarder proxy daemon for IPv4, IPv6 and UNIX stream sockets. It may be
used to bi-directionally forward traffic from a local listening socket to a local or remote destination socket.
One use of this tool is to provide socket activation support for services that do not natively support socket activation. On behalf of the
service to activate, the proxy inherits the socket from systemd, accepts each client connection, opens a connection to a configured server
for each client, and then bidirectionally forwards data between the two.
This utility's behavior is similar to socat(1). The main differences for systemd-socket-proxyd are support for socket activation with
"Accept=false" and an event-driven design that scales better with the number of connections.
OPTIONS
The following options are understood:
-h, --help
Print a short help text and exit.
--version
Print a short version string and exit.
--connections-max=, -c
Sets the maximum number of simultaneous connections, defaults to 256. If the limit of concurrent connections is reached further
connections will be refused.
EXIT STATUS
On success, 0 is returned, a non-zero failure code otherwise.
EXAMPLES
Simple Example
Use two services with a dependency and no namespace isolation.
Example 1. proxy-to-nginx.socket
[Socket]
ListenStream=80
[Install]
WantedBy=sockets.target
Example 2. proxy-to-nginx.service
[Unit]
Requires=nginx.service
After=nginx.service
Requires=proxy-to-nginx.socket
After=proxy-to-nginx.socket
[Service]
ExecStart=/lib/systemd/systemd-socket-proxyd /tmp/nginx.sock
PrivateTmp=yes
PrivateNetwork=yes
Example 3. nginx.conf
[...]
server {
listen unix:/tmp/nginx.sock;
[...]
Example 4. Enabling the proxy
# systemctl enable --now proxy-to-nginx.socket
$ curl http://localhost:80/
Namespace Example
Similar as above, but runs the socket proxy and the main service in the same private namespace, assuming that nginx.service has PrivateTmp=
and PrivateNetwork= set, too.
Example 5. proxy-to-nginx.socket
[Socket]
ListenStream=80
[Install]
WantedBy=sockets.target
Example 6. proxy-to-nginx.service
[Unit]
Requires=nginx.service
After=nginx.service
Requires=proxy-to-nginx.socket
After=proxy-to-nginx.socket
JoinsNamespaceOf=nginx.service
[Service]
ExecStart=/lib/systemd/systemd-socket-proxyd 127.0.0.1:8080
PrivateTmp=yes
PrivateNetwork=yes
Example 7. nginx.conf
[...]
server {
listen 8080;
[...]
Example 8. Enabling the proxy
# systemctl enable --now proxy-to-nginx.socket
$ curl http://localhost:80/
