The document I'm working right now has thousands of formulas and I've
been using the advanced search pretty heavily. I can detect the
increasing memory load even with the very simple text that I attached
(memory.lyx). I was continually searching for $e^{-x^2}$ and the
memory load increased steadily; much slower, but increased nevertheless...
strange, on my Ubuntu 11.04, no leaks show up on your example with the
search operation.
Actually, there's a slight memory increase the very first times you
launch the feature (the dialog objects are allocated, probably
translated Qt messages are loaded into memory, etc.), and a few other
times in subsequent uses. However, it goes steady and stable and it does
not increase any further, no matter how many other times I keep
searching, restarting from scratch, etc.
Also, I noticed a monotonic memory usage increase while editing the
document and especially creating math insets and deleting them later. I
guess this is due to the Undo feature, that keeps storing (a copy of)
all the insets even though you delete them from the document, until you
close the document (or probably save).
In your "workload pattern", were you simply searching, or also replacing
with advanced search ? In the latter case, if the replacements were a
lot, then this could justify the problem.
What Qt version is there ? Mine is:
libqt4-core 4:4.7.2-0ubuntu6.3
Thanks,
