    1. Do you know what version of kdb+ wrote the files?
    2. Is the data compressed?
    3. Are there attributes on any of the effected columns?
    4. Are any of the columns linked columns?
    5. If you go through the columns one at a time do their counts all match?
    6. Can you read the bad partitions in q and  write them to a temp HDB location. Do these rewritten files still show the same memory behaviour when you load the temp HDB?
