Error description

  • This hang can occur in an environment with multiple nodes or
    members.  It is subtle and does not have any specific
    characteristic or log a general point of failure.  You may
    notice that reads and writes are not increasing and that cpu
    usage for the application is very low.  The values for FCM sends
    and receives will also not be increasing.  To verify if you are
    encountering this issue a global application snapshot will be
    needed.  The snapshot can be restricted on the application
    handle.  The following command will gather a global application
    snapshot for all the applications currently running on the
    database.
    
    "get snapshot for all applications global"
    
    The following URL describes the get snapshot command.
