There is a regression with OpenOffice.org 3.1+ whereby opening certain documents
containing graphics results in high memory consumption and high CPU utilization.
Also related to this is a crash which I detail below.
With an 11 MB odt document, which I cannot attach, soffice.bin memory
consumption surpasses 300 MB and does not get released--even when the document
is closed--until the application itself is closed. I am, however, attaching a 1
MB excerpt of the document. With the 1 MB document, memory consumption exceeds
100 MB and does not get released when the document is closed.
The issue seems to be specific to something in the document, which was created
using OpenOffice.org 3.0. For comparison, I created a 12.5 MB document (also
with OO 3.0), with about as many graphics. This document opens quickly and
without any problems, soffice.bin consuming only 66 MB.
To reproduce the high CPU and memory consumption issue, simply download and open
the attached document.
The memory consumption bug existed throughout most of the 3.1 dev cycle and
continues to exist in the current 3.2 dev cycle (including the recent
DEV300m50). The bug does not exist in 3.0
THE CRASH: With the same document, for which the memory leak occurs, deleting
content then undoing results in a Microsoft Visual C++ runtime error and crash.
To reproduce the crash:
1. Download and open the attached document ("sample.odt")
2. Wait for the document to finish loading
3. Scroll to the last page
4. Select everything on the last page and delete it
5. Press CTRL+Z to undo
6. OpenOffice crashes.
note: Steps 3 and 4 may work with any content in the document, but this is how I
tested.
