APAR status

  • Closed as program error.

Error description

  • If you open a module in exclusive edit mode, a given amount of
    memory is consumed.
    
    However, if you open a module in read-only mode, then switch to
    read-only more, vastly more memory can be consumed.
    
    Testing with a module containing 5000 objects and 100 text
    attributes, each containing a small line of text, opening
    directly in exclusive edit mode consumed approximately 800MB.
    When first going via read-only mode, this figure increases by
    approximately 200MB.

Problem conclusion

  • The underlying design for this functionality cannot be
    easily changed.  Improvements have been made in memory
    handling to help reduce the occurrence of this.
