Error description

  • During a backup you see an Assert Warning in the online.log:
    
    16:55:10  Assert Warning: Archive detects that page 1:73354 is
    corrupt.
    16:55:10  IBM Informix Dynamic Server Version 11.50.FC9
    16:55:10   Who: Session(4535, informix@sirius, 25132, 1169af438)
                    Thread(4774, arcbackup1, 11696dbf0, 1)
                    File: rsarcbu.c Line: 4005
    
    Stack for this Assert Warning is:
    
    Stack for thread: 473055 arcbackup1
    oninit :: arc_pages
    oninit :: arc_dbspace
    oninit :: arc_scanner
    oninit :: startup
    
    This can occur when you use your data dbspace as a temp dbspace
    and there is a lot of
    parallel activity of dropping tables and hash join queries with
    overflow processing.
    
    Definition of the temp dbspace:
    
    DBSPACETEMP     ceus         # Default temp dbspaces
    
    Dbspaces
    address          number   flags      fchunk   nchunks  pgsize
    flags    owner    name
    ...
