      Description

      Martyn, please investigate the physical address exceptions in the log attached to BLZG-1418. My main question is whether this reflects a durable problem or a data race with a concurrent abort.

      For example:

      Aug 10 22:15:27 wdqs1002 bash[24866]: Caused by: java.lang.IllegalArgumentException: Unable to read data: com.bigdata.rwstore.PhysicalAddressResolutionException: Address did not resolve to physical address: -258530248
