[Bug 1317436] Re: onboard memory usage/cpu increase and lockup

[marmuta]

OK, I thought from comment #8 that the lockup issue was gone. Have you
been able to run Onboard in a terminal (xterm preferred) during the
latest lockup?

That graph is certainly interesting, the rise is >30MB/h, at least ten times as much as I see here on either Mageia or Ubuntu. My working theory is still that 1) and 2) have the same cause, i.e. the leak I reported is happening all the time, not just in thunderbird and synaptic. It's just more visible there due to those applications' tendency for high frequency bursts of at-spi events. See

If that is the case, then something must be continuously emitting 10
times as many events on your system as on your test install or on either
of my systems. Periodic terminal output in konsole or gnome-terminal
could do that. Are there and terminal jobs left that are running all the
time?

I don't want to rule out Onboard itself leaking, it wouldn't be the
first time. I'd even prefer that, it's way easier to fix for me, but the
evidence doesn't seem to indicate this is happening. Also, there are
many places that could leak, but a lot fewer without interaction. From
the top of my head, the only long-term idle activities are handling
incoming at-spi events and attempts to auto-save learned word-
suggestions (should do nothing when idle).

Things you can try:
- Run the leaktest1 sample from the gnome-bug report and monitor its memory usage. Does it show a linear increase too?

- Stop Onboard from listening to any at-spi events and monitor memory usage. Does it still rise?
gsettings set org.onboard.typing-assistance.word-suggestions enabled  false
gsettings set org.onboard.typing-assistance auto-capitalization false
gsettings set org.onboard.typing-assistance auto-correction false
gsettings set org.onboard.auto-show enabled false

- Turn off anything on your system that periodically generates text in
GUI applications, in particular in konsole and gnome-terminal (xterm is
fine), and monitor memory usage.
