    What are the differences between the server that works and the one
    that doesn't? I mean hardware and operating system details?<br>
    <br>
    Checking quickly the source code and comparing with logs, it doesn't
    reveal any problem -- it is about allocation of the next fragment,
    which was not used at all before, after the one allocated
    previously. The only reason I can think of it right now is corrupted
    memory or faulty OS.<br>
