Memory leak appearing in "unity-panel-sevice" arrives and disappears with Recent-Notifications

[Scott May]

I installed "recent-notifications" on both my laptop and desktop, and within days noticed a memory leak on both. On my desktop, after running for a period of several days the "unity-panel-service" was consuming over 8GB.

After removing "recent-notifications" I no longer have an accumulating memory leak in "unity-panel-service".

I can re-install and record any debug information you want, just let me know.

Sorry about the really late reply. I am usually emailed about new bugs but I never got this one.

I can actually see the memory increase a little bit after each 'notify-send'. I thought the indicator was cleaning itself up pretty well, but I guess not. Though interestingly, I don't really see much if any increase in indicator-applet-complete in the gnome flashback session, so maybe it is a problem with unity-panel-service.

I'm going to take a look and see if I can figure anything out.

Turns out there was a pretty serious memory leak in notification_new_from_dbus_message. I didn't think I owned the references to the GVariants, but as it turns out, I did.

Before the fix valgrind was telling me we were leaking about 1M per 1000 notifications.

I have pushed the fix out for 14.04, 15.04 and 15.10. I can push it to older versions if necessary, not sure which ones still have support.

Again apologizes about missing this bug for so long.

Hi Jason,

Thanks and good on ya' :)

Regarding versions - I think the three versions you mention are the only
ones worth worrying about.

Have a great day!
