Re: org.janusgraph.diskstorage.TemporaryBackendException: Wrote claim for id block

I'd suggest trying to increase the ids.block-size, and perhaps adjusting the ids.renew-percentage.

No idea what your graph loading code looks like, but you might want to commit() transactions in smaller batches.

Also check out http://tinkerpop.apache.org/docs/current/tutorials/getting-started/#_loading_data
