[strongSwan] charon appears to either crash and/or restart during HA takeover

Hi Dave,

While there is a similar log message in the upstream ha plugin (ours 
logs the system error too), you seem to be using a patched version (all 
those "HA:" log messages are not in our code base, neither does the 
upstream plugin use sockets that could be reset/disconnected).  So 
please contact the devs of those changes.

Depends on your system settings.

Not since 5.8.0, but using current versions is recommended anyway.
