    Re

    I think reserve page of this chunk is corrupt ,
    the solution (have to trial) setup another instance then add this chunk (not being primary chunk) for rebuild reserve page so shutdown this instance and start the first instance , if it's the same , you have to config database to skip the dbspace that own this chunk drop/create

    Before doing anything, you should check this file:
    /tmp/af.72e547e
    A lot of information can be found in this file.
    For instance, you can see the stack trace of the thread causing the crash.
    rws
