Title: ubuntu-weather-app is polling poll() at 15Hz and heap is growing at 1K/sec on idle Status in Ubuntu UI Toolkit: Incomplete Status in Ubuntu Weather App: Invalid Status in ubuntu-ui-toolkit package in Ubuntu: Incomplete Bug description: On an idle phone, the ubuntu-weather-app is polling poll() at 15Hz. Also, I am observing heap growth at about 1K/sec. CPU usage: PID Process USR% SYS% TOTAL% 3177 qmlscene 0.24 0.48 0.72 (very light load) System calls traced: PID Process Syscall Count Rate/Sec 3177 qmlscene poll 8991 14.9849 Change in memory (K/second): PID Process Type Size RSS PSS 3177 qmlscene Heap 1.71 1.20 1.20 (growing) So it's not entirely idle and consuming power when doing apparently nothing. The heap growth is observable from the the /proc/3177/smaps information, however, I can't see any obvious sbrk()/brk() or mmap() calls, so it is curious how this is occurring. Observation: I am noticing this with all application which are launched using qmlscene and suspect it could be qmlscene which is leaking memory. The symtoms that I see are laggy UI when leaving a qmlscene app launched for several hours while on suspend.
