Greetings,
I have several servers with consumer grade hardware all running great with 9.1-RELEASE but one keeps freezing after some days, sometime it freezes even only after a few hours since server restart. Furthermore this is the only server with high load averages and high interrupt/idle for CPU1 (This is an Intel Pentium G630T 2.3 GHz dual core CPU on Intel H61 chipset) even when idle. None of the other servers have these problems.
The server was upgraded from 9.0-RELEASE (I don't recall any problem then with 9.0-RELEASE) and is a dedicated router/firewall with 3 NICs, 1x onboard Realtek and 2x from an Intel PT/1000 dual port, all gigabits:
Network load is not too high (see caption below). Appreciate any help urgently as this server is in production and link the rest with the outside world. Thank you so much.

- Runs PPPoE, PF, OpenVPN and Avahi (configured to route Bonjour's zero-config between private subnets).
- Realtek is connected to ISP's broadband modem.
- Intels each connected to different private subnet, one is jumbo frame (MTU 9000) only subnet.
Network load is not too high (see caption below). Appreciate any help urgently as this server is in production and link the rest with the outside world. Thank you so much.
