Error description

  • DOORS crashes with diagnostic logs while trying to filter on
    suspect links for out-links (all modules)
    
    If a module has out-links to a large number of modules which are
    of huge size, filtering on suspect links for out-links (all
    modules), generates Diagnostic logs and DOORS goes into
    non-responsive state.
    
    Steps to reproduce:
    - Create a module that has about 2000 out-links to over 35
    modules (each of which is 500M - 1G in size)
    - Click on 'Analysis -> Suspect Links -> Filter -> Outlinks (all
    modules)'
    
    Expected Results:
    Filtered objects should be displayed
    DOORS should not go into non-responsive state
    
    Actual Results:
    DOORS consumes over 99% of system memory, continually generates
    Diagnositc messages and goes into non-responsive state.
    Filtered objects with suspect out-links is not shown.

    ****************************************************************
    The defect was caused by the algorithm of finding suspect
    links. Old algorithm was loading all modules out-linked and
    then performed checking for suspect links. This could use
    huge amounts of memory and in some cases could lead to
    generate "System Memory Exhausted" error message.
    

Problem conclusion

  • Proposed solution checks module a time and releases
    resources used after adding objects to filter.
