Title: Slow DNS above 7K sessions/states (torrent)
Post by: rudiservo on June 25, 2026, 04:59:22 PM
I am having sort of an issue with Unbound taking a long time to respond to a query when I turn on qBittorrent.
I tried tweeking Unbound but it hasn't made that much of a difference.

The network is fine, ping is fine, speedtest is fine, qBittorrent has speed limits, its really just unbound taking a long time to respond to a query.
A dig command with @ my router sometimes results in a timeout.

Anyone has any advice on how to deal with this?

Did you check if the firewall state tables gets exhausted? If so, increase Firewall ➔ Settings ➔ Advanced : Max States
