Error description

  • To Reproduce:
    - configure DOORS to communicate with DM or RQM
    - Disable link discovery for DM or RQM in the Remote Services
    tab
    - enable link discovery for your user in Tools-> Options
    - create a new module with some plain objects let's say 1000
    - save the module and close DOORS client
    - restart DOORS client and check the system Task Manager, you
    will observe 'doors.exe' would be around just 160 MB.
    - open the newly created module
    - OAuth login window will appear so please log in
    - link discover will be started for this module which has no
    links.
    - While the Link Discovery is progressing on the Module, observe
    the Task Manager and 'doors.exe' will keep gradually increasing
    and by the time it finishes the Discovering links operation, the
    memory would have grown upto around 500 MB.
    - If you close this Module now, the memory consumed doesn't get
    released and 'doors.exe' would remain at about 500 MB.
    
    As another test, on a Module with 10,000 Objects with just
    'sample test' added in Object Heading (i.e the Module in itself
    isn't bulky in itself with data in Objects etc).  Memory grew
    from 160 MB to appox 3 GB and when the Module was closed, the
    memory wasn't released.
