Subject java exception on start
Date Sat, 12 Jan 2013 17:51:45 GMT
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

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

Thanks,
Tim
