After being away for nearly 2 weeks, this past Monday I pacman -Syu'd and updated chromium, some xorg stuff, and linux to 3.2.13-1.
Now I'm noticing that with regularity my wifi is dropping completely. It can happen twice in 5 minutes then not happen for an hour. It's completely sporadic.
To reconnect I must pkill dhcpcd and wpa_supplicant, then run my wifi shell script. However, when I add "pkill dhcpcd" and "pkill wpa_supplicant" to the top of my wifi script (to make the process faster) I get the following error:

Does anyone know why this is happening?

Not a fix, but maybe a workaround, definitely a data point -- What happens if you use dhclient instead of dhcpcd ??
