pfBlockerNG 2.2.5_27 cron update and traffic loss

[asdjklfjkdslfdsaklj]

Recently updated to 2.2.5_27, and since then I've noticed traffic loss (established connections failing) during the hourly update process.

System logs:

Dec 8 10:06:30	php		[pfBlockerNG] No changes to Firewall rules, skipping Filter Reload
Dec 8 10:00:00	php		[pfBlockerNG] Starting cron process.

Things start failing right around the "no changes to firewall rules" message, and after about ~30-45sec previous connections re-establish (new TCP sessions), and new connections can establish.

Sometimes, but not always these messages are seen as well:

sonewconn: pcb 0xfffff8022bb13000: Listen queue overflow: 8 already in queue awaiting acceptance (1 occurrences)

Haven't noticed a spike in CPU, memory, etc. during this process.

Any thoughts regarding where to look further?

Let me guess, that is the time unbound (the dns cache + resolver) takes to restart ?
And will it's going down, and restarts, during this tame : no more DND cache, no more answers to DNS requests.
( compare captivity of your logs mentioned above with the DNS log at the same time )

Looks like "kill states" being enabled was killing things. This wasn't happening previously, so need to ascertain whether or not an erroneous item in a list is causing this to fail before recovering, or something to do with pfBlockerNG itself.

As an aside, no, no issues with name resolution.

Well, I'm still curious to know what the time is between "unbound stop" and "unbound started".

None, given "Resolver Live Sync" is enabled.
