Error description

  • Target server can crash under the following conditions.
    
    Source server has container pool(s).
    Target server has container pool(s) with nextstgpool configured
    Protect stgpool is run on source server
    Replicate node is run on the source server.
    Target server container pool(s) has no free space and thus
    nextstgpool has to be used.
    
    During "replicate node", the target server can crash when trying
    to write the data to the storage pool
    defined by the nextstgpool option for the container pool.
