Re: [Bigdata-developers] " No WriteCache debug info"

Typically this indicates an actual disk error. It is attempting to read
data from the backing file. The checksum that was stored is not matched by
the data. The only time I have see this was when there was actually a bad
disk.
Caused by: com.bigdata.util.ChecksumError:
