the above is caused probably all the time, but not noticeable until
heavy load.
The system becomes vary sluggish, hulu craps out, radio craps out
(not fun)...
When you say heavy load, do you mean heavy network load (traffic) or
system load (CPU)? I think there are timeouts in the key exchange
which might fail if the system were really loaded. Then again that
probably wouldn't effect established connections. The snippet below
looks as if the connection was dropping and resetting, may be a driver
issue.
After disabling NetworkManager and compiling wpa_supplicant from
the source(using the default .config they supply for compiling)
wpa_supplicant looks like this:
[name@name wpa_supplicant]$
sudo
/home/name/Sources/wpa_supplicant-0.6.9/wpa_supplicant/wpa_supplicant
-Dwext -ieth1 -c /home/name/wpa

still shows some errors, but I'm able to stream music, plus watch movies
without having a sluggish system, nor having stuckage of internet.
I would file a bug, but there probably already is, since this is
something I've seen for some time now right!

Using a humble old Celeron laptop and FC11, doing
ssh host2 "dd bs=5k count=50k" </dev/zero >/dev/null
doesn't show much CPU in use.
Casual test, one line and 'top' to see who uses CPU.
Thanks for the bug#, will follow there.
heavy load as in internet traffic.
(could be high cpu load as well).
As for the whole wpa_supplicant crapping out thing,
I did experience sluggishness but after looking into it
I think it was readahead. i.g. compiling libc from git went good,
but after a reboot readahead did not like that(segfaulted and gave the
same slow sluggishness as I experienced earlier before a libc compile
and install).
After uninstalling readahead the system seems to be stable, but I
probably will hit that
wpa_supplicant thing(if I don't use the source version I compiled).
From what I remember when this happened when I used debian/ubuntu I
ended up downgrading
wpa_supplicant, and the key exchange reacted as it should(at the moment
I dont have a wpa network
but it is happening without encryption as well).
Now worries, just one of those things..
