Package: iceweasel
Version: 24.2.0esr-1~bpo70+1
Severity: normal
Dear Maintainer,
I found that the 24esr version of iceweasel (linux debian 7.3 stable, x86-64
laptop, dual-core Intel Core2 duo) often causes 100% CPU utilization upon
resuming from sleep. I don't know which tab causes this though. I have a
suspicion that perhaps gmail is the cause (since I always have that open), but
I am not sure.
I have noticed that this issue also exists on the mainline version of firefox
(specifically, "aurora" branch up to version 27; perhaps v 28 also have it but
I don't know that for sure).
This is what typically happens:
- I close the laptop and it goes to sleep-to-RAM
- upon resuming, I notice the CPU being hot--and iceweasel uses 100% CPU. Also,
xorg uses about 50% CPU
- I tried to close tabs one by one, it did not cause the CPU usage to decrease
- nevertheless, iceweasel is still fully responding and functioning (but
somewhat slow, of course)
- I tried to close the program, the iceweasel GUI window(s) was closed, but at
the same time, the CPU utilization goes > 100% (i.e. all two cores were
occupied by iceweasel), often to ~200%.
- The only resort is to kill the process using "kill" command and restart
iceweasel.
- Comment: The last time I noticed this problem, the laptop was plugged on AC
before sleep, and was on battery upon resuming. Also I woke the laptop up in a
different building (thus, different wi-fi SSID).
Too bad that firefox/iceweasel does not have tab process viewer, akin to
“ps” that can show CPU utilization per thread. I imagine this is not too
hard to do for one who knows the code well.
This is a very annoying problem that I have noticed for many months. I decide
to report this, in case someone can help pinpoint the issue. I have not
restarted afresh with a blank profile (I have too much information deposited on
my current profile.)
