i am seeing a lot of these INFO level messages in cassandra server's logs:

2010-03-08 15:30:08,123  INFO [pool-1-thread-625] [StorageProxy.java:485] DigestMismatchException: Mismatch for key vmguest85__1349889195 (076e19c042e3756a619a8b3fcdd1b9f2 vs 6a2d12aebba5c51c1d9a60cd0ec556d9)

anything to worry about?

thx
