checkpoint write errors

    Hi all;
    we're seeing the below errors over and over in the logs of one of
      our postgres databases. Version 8.4.22
    

    Anyone have any thoughts on correcting/debugging it?
    Maybe I need to run a REINDEX on whatever table equates to
      "base/1029860192/1029863651"?  If so how do I determine the db and
      table for "base/1029860192/1029863651"?
    

    LOG:  checkpoint starting: time

        ERROR:  xlog flush request 2571/9C141530 is not satisfied ---
        flushed only to 2570/DE61C290

        base/1029860192/1029863651

        DETAIL:  Multiple failures --- write error might be permanent.

    
    Thanks in advance
