TOR stopps running and doesn't restart

Hey,

I have a TOR middle relay on a 64MB ram VPS. I set an AccountingMaxLimit so the server should stop when it reaches 8GB in one way. And this should be resetted everyday at 00:00, but the TOR relay doesn't start again. I don't know if the server crashs or if it's because of this limitation and the TOR relay doesn't start again. My other TOR relays run great.

What can I do?

Thanks in advance!
