Wifid on Paperwhite - zombies

Cykotitan · 06-13-2013, 06:33 PM

The story starts with my WiFi network dropping out at seemingly random times of day, 3-5 times daily. After each of these dropouts I'm unable to connect to any network even though they get listed properly.
Errors include "check your local network" and "auth/security type does not match the network's type".
The only fixes so far seem to be a restart, and more recently discovered: turning airplane mode on and off. I assume killing wifid would do just the same.
Another thing I've noticed is wifid spawning numerous 'sh' threads which run shortly before turning zombie (Z).

My question follows, is there any correlation between my issue and task spawning, or is it normal behavior?
I cannot recall what I did at the time this issue first appeared, but I would like to resolve or workaround this problem of mine without resetting my device or reapplying an update, as without PC access I would be stuck and prevented from reapplying the jailbreak, and left unable to perform my usual activities with that.

Not normal operation.

Change the columns to display PPID so we can see what process spawned those zombies.

Also, that output is limited by the number of lines on the display.

Use:
top -bn1 >to-some-file-name.txt

PPID matches wifid PID
Wasn't able to upload files from kindle, used SCP instead as usual: http://m.cinara.net/top.txt
At the time WiFi is broken, there are above 1050 tasks total, 1000 of them being zombie sh threads.
ifup wlan0 says interface is already configured, and wifid occasionally runs some task with ifup wlan0, writing to /var/log/udhcpc.log and doing something with the udhcpc utility.

Permissions error, changed.
See also http://cinara.net/netlogb.txt, but I'm thinking it's just more of the same...
