[Tor-BSD] experiences with tuning BSD boxes for Tor?

I was running a non-exit relay node on a Raspberry Pi B running FreeBSD
at home but last week it seems to have crashed under the load.

Short config:
- Raspberry Pi B, 496 MB RAM, 100 Mb/s ue0, 700 MHz
- FreeBSD 10.0-RELEASE-armv6
- 35 Mb/s down / 4 Mb/s up DSL line
- Tor bandwidths (normal/burst) set to 500 kB/s

Does anyone have some tips on what (if any) kernel parameters to set?
The default kern.ipc.somaxconn value of 128 seems to low for any real
traffic, but 32768 deprives the kernel of any mbufs in just 20 minutes.

It might be that a RPI is just too small to be a reliable relay...
