A funny thing happened the other day... I powered on my N900 and all desktop icons had disappeared, and along with them the functionality of the desktop edit menu that would let me add apps and widgets back in. In fact, the Desktop Menu simply fails to appear.

Worried that maybe my "Memory for installable applications" drive space was getting too low (39.2 MB available) , I tried starting application manager to remove some cruft, but application manager won't get past looking up the package libraries - the busy indicator just cycles.

So... in theory you can fix anything and everything from bash. For everything else, there's Device Reflash.

Has anyone else encountered this problem? Is there a fix, or do I really have to reflash my device because it decided to just randomly have this aneurysm?

This might indicate to a full rootfs like you are suggesting.
Try to reboot, sometimes only the hildon-desktop-process or the like has just died, then open X-Terminal and get some info
Code:
df
mount
ls -al /home/user/MyDocs
If you have rootsh installed and also did some tinkering with the device's partitioning please
Code:
sudo gainroot
sfdisk -l #this is small L not 1

I would add as well that the activity on the device has been consistently high. With nothing else running on the device, Conky reads it as redlining at 850 Mhz 100% with the power kernel, and the various hildon routines are using up most of the top CPU%, Memory, and CPU Time. I'd thought trackerd might be the problem as I renamed my a news archive's top-level directory, but it only shows up in Top I/O on occasion, so I hope it's finished indexing that content, it's been a couple of days already.

There's also an ongoing connection to provo.static.broadweavenetworks.net on lport 60583 but I think this has something to do with Skype or Funambol.

In top, instances of skyhost -x -s /tmp/skyhost are also showing up. Could that be the problem? I see people had a 'skyhost bug' on the n8x0.

Edit: at rest, /usr/bin/hildon-home is presently eating around 60% - 90+ % of CPU

Thanks!

Your optfs on the partition for /home is full. Try to analyze with
Code:
du -kx /home | sort -n #this time it is neither l nor 1 it is a  | 'pipe'-symbol
This will list all folders on the /dev/mmcblk0p2 partition sorted by size starting with the smallest. As this will be quite a long list it will scroll out of the buffer of X-Terminal, but because only the biggest folders are important.

If this does not indicate some real space wasters there is the slight possibility, that your MyDocs partiition is or was temporarily not available, while still some copying was done to that folder.
You could check
Code:
sudo gainroot
umount /dev/mmcblk0p1
du -akx /home/user/MyDocs
If anything is listed move it away to free the space then remount the partition.

Removed OpenArena, which should have helped.

Hmmmmn... the umount command keeps telling me Device or Resource Busy. I can't -f force unmount it either. I'll wait an hour or so and try again.

You could list the processes that access MyDocs with
Code:
lsof /home/user/MyDocs

Try
sudo killall hildon-home
or/and
sudo killall hildon-desktop

from time to time I also run into similar phenomena, loosing all desktop shortcuts, killig home gets me back to working state. Then putting back a save copy of home.plugins
with
cp /home/user/.config/hildon-desktop/home.plugins.save /home/user/.config/hildon-desktop/home.plugins
gets me completely back.

I did end up having to reflash the device. Took me a day and a half to get everything working back the way I like it. Now gPodder has begun refusing to run, and I blame trackerd faulting somehow but can't prove it. But that's another story. Thanks for trying to help me get my device going again.
