I run a few Rasp PI relays. If you use Tor 2.3.5 you need to limit bandwidth to 100KB or less and make sure the CPU is not overclocked to avoid heating issues unless you stick it in the fridge or something.

2.4.17 is much better at dealing with circuit storms, i can push 3Mbps upstream with no issues. 

try setting up cron if it keeps crashing. eg.

*/15 * * * * /etc/init.d/tor start

I don't think it would make a difference. When my relay is experiencing
a circuit-creation storm, I've restarted Tor, and even stopped it for a
few minutes, but as soon as it comes back online, it gets slammed
again. Only leaving it offline for an hour or so and then turning it
back on seems to mitigate the problem.
