Gateway switch events cause a huge amount of log spew
0%
Description
When a gateway failure/defgw switch event occurs, there seem to be some code paths that get iterated over dozens of times in a very short span of time. This floods system.log making it hard to read. Specifically, these 2 phrases are repeated over and over:
Gateways status could not be determined, considering all as up/active
Keep current gateway, its already part of the group members
This is part of an effort to try to make the logs readable again, while still allowing verbose logging if needed via a new hidden config option from the developer shell:
$config['system']['gw-debug'] = true;
write_config("Enable Developer Spew");
exec
exit

Replicated in 2.4.4-RELEASE
Steps to replicate:
Configure Gateway Group with 2 WANs
Start Tier 1 down, Tier 2 up
Connect Tier 1, wait for link to configure, disconnect Tier 1.

Had different results each time, in each of 3 tests there were 2 entries, 5 entries, and 7 entries for that message.

Tried to replicate the issue in 2.4.4-RELEASE.
Under logs, I was getting only "Keep current gateway, its already part of the group members" but only a couple of such logs. There wasn't any flood.

Could you please check if you are also experiencing latency spikes on LAN Interface during a reconnect (run a ping to pfsense LAN IP and reconnect? You might be having an issue I am trying to troubleshoot in the Forums for a few days.

Not sure what the acceptable level of log spam is:

That is a Gateway down and up event cycle.

Tested on VM HA cluster - CE 2.4.5-DEVELOPMENT (amd64) built on Tue Nov 20 16:55:31 EST 2018:
No "Gateways status could not be determined" events in syslog on gateway failure's (disabled tier1 WAN on primary node then enabled it back) - ran icmp from host on lan behind HA cluster - no latency to LAN or 8.8.8.8 during gw up/down events. Just 1 lost icmp packet on HA failover to secondary as it should be.
Not seeing any issues.
