> This occured on two nodes on me (running 0.7.1 from svn)
> One node was killed by the kernel due to a OOM and the other node was haning and I had to kill it manually with kill -9 (kill didn't work). (maybe these were faulty hardware nodes, I don't know)
> The saved_cache was corrupt afterwards and I couldn't start the nodes. 
> After deleting the saved_caches directory I could start the nodes again. 
> Instead of not starting when an error occurs, cassandra could simply delete the errornous file and continue to start?
