Hello,

 I just upgraded to cassandra 1.2 and I notice that when I start the node I see this java exception:

 WARN 12:46:52,872 error reading saved cache /var/lib/cassandra/saved_caches/system-schema_columnfamilies-KeyCache-b.db

Yes it's a warning and not anything critical. Cassandra does start. The node operates and serves my website (all cassandra based). I'm just wondering if this is something I should consider correcting and wether it will impact the nodes performance.

 Here's a listing of that file that it's complaining about being able to read:

 -rw-r--r-- 1 root root 61 Jan 12 12:07 /var/lib/cassandra/saved_caches/system-schema_columnfamilies-KeyCache-b.db

Thanks,
Tim
