Memory leak (in Conky/python/curl?)

nathan28 · 2011-09-22 15:39:27

I'm showing ~35% mem usage on 4GB RAM with only one Firefox tab and two urxvt windows open. I'm getting conflicting information.

It looks like conky and firefox have both grabbed about half a gig together--even when I kill both and restart.

# archey says RAM: 1120 MB / 3020 MB
$ conky | dzen says 36%
# top (by mem) puts firefox at 5%, X at 1.4% and conky at .1%

But here conky isn't calling on that much by itself. Conky updates every 2 seconds and my config is:

${execpi 300 ~/Scripts/mail_counter.py} email(s)  |  ${addr wlan0}  |  BATT:${battery_short}  |  RAM:$memperc%  |  CPU: ${cpu cpu1}% ${cpu cpu2}%  |  FREE root ${fs_free /} home ${fs_free /home}

mail_counter.py is from the wiki IIRC. I didn't see python eating that much in memstat. There's that 2MB of curl but that's about it.

Lastly gmemusage portrays Firefox at ~300MB, Conky at 164MB, console-kit at 87MB, polkitd at 82MB, and udisks at 83MB.

Where's my RAM going? I had forgotten to plug my battery in and had to boot up just 15 hours ago X(

EDIT: Just rebooted, got to POST and GRUB and then got a black screen and bunch of beeping after selecting the regular kernel, which IIRC means RAM hardware issue. Able to boot into the fallback kernel fine, and into the regular one again after that. going to do a memtest.

Post the output of 'free -m'.

nathan28 · 2011-09-22 16:59:27

I just ran memtest, so this is probably not helpful but this is what it looks like after a reboot running the same applications:

total       used       free     shared    buffers     cached
Mem:          3020        421       2598          0         23        131
-/+ buffers/cache:        266       2754
Swap:         4095          0       4095

I am going to attempt to replicate this by ensuring that firefox & conky stay up for a few hours.

The apps are using just 266 MB of RAM https://wiki.archlinux.org/index.php/FA … _my_RAM.3F

nathan28 · 2011-09-22 17:37:33

No, this is after reboot--earlier free was showing closer to 1GB by the apps after 15 hours uptime

Is that whole conky config? Are you using LUA scripts by any chance?

nathan28 · 2011-09-22 18:56:33

That's the whole config, piped into dzen2. Only script running is the one in that conky config:

#! /usr/bin/python

import os

username=[foo]
password=[foo]
com="wget -q -O - https://"+username+":"+password+"@mail.google.com/mail/feed/atom --no-check-certificate"

temp=os.popen(com)
msg=temp.read()
index=msg.find("<fullcount>")
index2=msg.find("</fullcount>")
fc=int(msg[index+11:index2])

if fc==0:
   print ("0 new")
else:
   print (str(fc)+" new")

Daemons running should have been: alsa, crond, cupsd, dbus, iptables, netfs, ntpd, sensors, syslog-ng, thinkfan, wicd.
