I would call 1.0.7 rock fricken solid. Incredibly stable. It has been that way since I updated to 0.8.8 really. TBs of data, billions of requests a day, and thanks to JAMM, memtable type auto-tuning, and other enhancements I rarely, if ever, find a node in a state where it requires a restart. My clusters are beast-ing. There always is bugs in software, but coming from a guy who ran cassandra 0.6.1.Administration on my Cassandra cluster is like a vacation now.
