I have seen similiar bug reports,but these are really old and are not related to version 16.10. This is way I'm opening a new one.
Currently the unity-panel-service process uses about 11GB of RAM which is definitely too much

# Impact
The bad behavior of owncloud-client, combined with a design issue in Qt 5, and with unity-panel-service not cleaning up after old indicators, cause huge memory consumption of unity-panel-service. The consumption grows in arithmetic progression and can quickly reach several GBs.
For technical explanation of why this happens, see my comments #17 and #19.
I could not figure out how to explore the Unity panel contents in the GTK+ inspector. If that is possible, then the big row of the dead hidden indicators should be shown there.
# Proposed Fix
Fixing either unity-panel-service or owncloud-client will both work. In owncloud-client the fix is just one line, so it is easier. It disables the upstream workaround which was only needed for Qt 5.5. Upstream has also limited the workaround to Qt 5.5.0 only in newer code, so this patch will no longer needed with the next major owncloud-client release.
The same patch has been applied in Zesty version 2.2.4+dfsg-2ubuntu1.
# Regression Potential
Both bugs that the workaround took care of are fixed in Qt 5.6:
- https://bugreports.qt.io/browse/QTBUG-47863 — fixed in 5.5.1, 5.6.1
- https://bugreports.qt.io/browse/QTBUG-48068 — fixed in 5.6.0
So this should not cause any regressions.
# Test Case
Just start owncloud-client under Unity (and make sure it shows the tray icon). Logging in is not necessary, though that increases the memory consumption rate (as there are more menu items).
