IP address change triggers reload of all packages
When OpenVPN restarts and the clients or servers are assigned to interfaces, the packages are reloaded. They are even reloaded when the ip has not been changed at all...
Here the log showing two things. First, the real interface: ovpnc1 is known the the newwanip "process". Secound, the ip change of 10.40.91.2 -> 10.40.91.2 restarts packages.

There are some packages that might like to know about interface state changes, including changes where the interface "goes away and comes back" in some way, even though the IP address... come back the same as previous. In the current system there is no standard interface to notify packages of changes, thus the brute-force package restart.
I seems to me it would be good to provide some better standard package notification method that can pass to packages some detail of the event and then each package can choose to ignore the event, restart completely or reload its config or do whatever it thinks appropriate.

as Phil noted it's not as simple as not doing this, as that breaks other situations that require it.

User "Kill Bill" wrote a patch that disables this behaviour for 2.2.2 and linked it in https://redmine.pfsense.org/issues/4868.
This is the same code, just ported to 2.3.2.

Just FYI: That's not my patch, see the URL :)
