Light browser chews up 100% of the CPU power
Posted: Mon 29 Jun 2020, 08:07
The Light browser falls into an elephant pit.
I am running uPupBB (the 32bit busy beaver) on a Pentium P4.
So: Pentium 4 CPU 3.00GHz Speed of Core 0:3000 MHz, 1:3000 MHz
Core Count: 1.
Memory Allocation: Total RAM: 2004 MB, Used RAM: 1205 MB
Free RAM: 799 MB Buffers: 67 MB Cached: 629 MB Total Swap: 255 MB Free Swap: 90 MB
Distro: BionicPup32 19.03
Observations of the fault.
Light: 48.0
The fault is evident when playing 'youtube'. The fault MAY involve scripts/ads, but this is only a guess.
When Light is running 'normally' CPU usage can be 15 .. 40+% when 2 or 3 tabs are open.
The first indication of the fault: CPU usage creeps up toward 80 .. 90 .. 100%
Another indication: I hear the fan speed increase.
Another indication: The sound (at first) becomes 'clipped'.
After this the sound starts to 'stutter'. If I do nothing the interval between the stuttering grows and then I hear distinct 'gaps' in the sound. At this point I go to the task-bar and try to kill Light. After some pause I see the menu 'close/kill/maximize ...' If I select 'kill' (the only real option at this stage) some time later (seconds or even a minute the confirmation box appears. I read "I may lose info if I continue". I click 'OK'.
This is the interesting bit. The message box disappears and Light also disappears, but the sound (with long gaps) continues. It can take 10 seconds or several minutes before the (broken) sound stops. At the time the sound disappears the fan-speed drops. To comment on 'broken' sound. I hear short 'grabs' with silence between the 'grabs'. It seems that the task swapping proceeds in discreet 'chunks' with some considerable interval between the sound 'grabs'.
The fault completely ties up every process on the desk-top. I can also re-gain control by pressing <ctrl> + <alt> + <backspace>. For me the fault is frustrating. For most people, they would take an axe to the computer (or go back to Windows).
The question: What causes this problem and how can it be solved.
Final comment: I'm running uPupBB 32 as downloaded from the 'official' page.
All the best!
