18.7 Legacy Series / Flapping WAN connection not handled well with Multi-WAN + unbound
« on: July 11, 2018, 11:21:45 am »
If a WAN connection is flapping, services restart repeatedly. This means that even if that connection is at a low tier in gateway groups and not in use it has an impact on services.
Unbound isn't very speedy to restart either, so the negative impact is high. It can be effectively down when a connection is flapping every 20 seconds.
Can we avoid restarting unbound in this case? (Is a reload sufficient?)
edit: Modified title as this seems to be an unbound specific issue
