> I've seen this a few times - the output for LRU stats ends up with some invalid characters
in it:
> 11/03/03 14:36:06 DEBUG hfile.LruBlockCache: LRU Stats: total=1.49 MB, free=180.56 MB,
max=182.05 MB, blocks=0, accesses=0, hits=0, hitRatio=�%, cachingAccesses=0, cachingHits=0,
cachingHitsRatio=�%, evictions=0, evicted=0, evictedPerRun=NaN
> Note the messed up "hitRatio" and "cachingHitsRatio". I can't figure out how to reproduce,
though.
