APAR status

  • Closed as program error.

Error description

  • Open a module with lots of baselines (40/50+)
    In this test in Task Manager the memory usage is 107 650k
    In Object Properties>History Tab select "Load Previous" and do
    this for 40/50 baselines
    Task Manager shows that memory usage is 2,656,284k (will depend
    on data in baselines)
    Close the formal module the memory usage doesn't really change.
    To release the memory used to open the baselined modules, select
    Tools>Manage Open Modules and close the relevant baselines.
    Memory usage drops back to 154,064k
    
    Now open a completely different module that also contains lots
    of baselines
    Select Object Properties
    In Task Manager you can see memory usage increasing again as
    DOORS opens baselines in this new module.
    
    If modules in the DB typically have lots of baselines memory
    usage for the DOORS.exe can very quickly reach 2GB. This is
    obviously a problem for 32 bit clients.
    Also tested this in DOORS 9.6. Same behaviour
