Red Hat Bugzilla – Bug 515029
wpa_supplicant craps out under heavy load.
Last modified: 2009-11-19 14:16:27 EST
Description of problem: wpa_supplicant disconnects, and reconnects under heavy load, causing the system to become sluggish, and internet timeout.
Version-Release number of selected component (if applicable):
(whatever fedora 11 comes with)
load a radio station online, then watch anything in flash longer than ten minuetes
(watch a movie on hulu).
Steps to Reproduce:
2.open mplayer play your favorit streamed radio.
3.open firefox watch a movie on hulu.
hulu stops playing radio stops playing,
system becomes sluggish.
watch a streamed movie, and if you would like mute the video, and play radio
(kind of like watch old silent flicks!)
download the source code of wpa_supplicant and compile the source using
the default .config should work.
not sure where this is at. I guess you can close this, since there seems to be no comments/complaints on this bug. As for a fix like above I just recompile wpa_supplicant, and all is good.(keep in mind the.defconfig is as is, nothing added/or removed).
This is probably more the driver than anything else. Does the kernel 'dmesg' logs say anything interesting from the driver?
well, with the two machines I've seen this on both,
one machine is a macbook pro(using ath9k) and the other is an imac using broadcom sta.
There is nothing in dmesg. the only way to really see anything
is to manually run wpa_supplicant in a terminal(no networkmanager/wicd...)
(usually will fire off under heavy load).
When you say heavy load, you mean heavy network load, not heavy CPU load, right?
What is the supplicant output when this happens? When you manually run the supplicant, can you run it iwth the "-dddt" option to increase the logging verbosity for me?
keep in mind I don't have the issue in front of me right now. But I do remember what wpa does.
basically I would do this:(in a terminal)
wpa_supplicant -Dwext -i wlan0 -c /etc/*
(wpa_supplicant starts, then I use /sbin/dhclient wlan0)
then wpa will print out connected.
then I turn on an internet radio station then open firefox ant turn on a video
i.g.normally go to hulu.com and watch a movie(while the radio is playing as well).
then after a few minuets I would see wpa_supplicant in the terminal
(during that period, is when the music starts to die out, as well as the movie).
Ok, if you get a chance to reproduce the issue, if you could use "-dddt" with the supplicant's command line, and also when you get the dropout, grab the last 20 or so lines of /var/log/messages for me. Thanks!
right now I don't have fedora installed, but I do have the livecd,
What I can try is load the livecd hopefully get the wireless driver compiled
and then try and grab the debug message.
Ok, let me know!
man I feel so stupid. just loaded the livecd got the wireless working with flash, and mplayer running, and to my surprise the system had no issues at all, leading me to believe that this was something done wrong on my behalf i.g. the only thing I can think of is my .config is missing/configured in a way to fire this off.
I apologize for filing this report without really testing this.
No problem; I more suspect driver problems too though. If this happens again, please reopen. Thanks!
Thanks for being patient with me..
