Symptoms:

- Maemo Mapper crashes during startup. The launching banner appears and then disappears. Maemo Mapper is not listed in the output of "ps aux".
- The root file system is nearly filled by the crash. Before the crash 59 MB were free. Post-crash free space varies: 2.6 MB after the most recent crash, 1.6 MB and 1.2 MB free after the two previous crashes.
- The system becomes inoperable. I assume that is due to the small amount of amount of space on the root file system. Immediately after a boot, I can open an xterm and check a few things before the system slows to a halt and reboots. I can use "df -k" to find out that the root file system is nearly full, and I can use top to find out that the jffs garbage collector and maemo-launcher take up the most CPU time. Then, the system reboots on its own. I cannot use "du -sk" to find out where the space has been consumed because it never returns (and never really uses any CPU time as shown by top).
- The only method that I have been able to use to recover is to re-flash the 770 and install everything anew.
- I've experienced three such crashes, widely separated in time, meaning that I've gotten a lot of good use out of the mapper between crashes. The first two crashes were with unmodified Maemo Mapper 1.4.7-2. The current crash is with a version that contains modifications that I have made - a version that worked very well on two 12-hr days of driving.
- Each of the three crashed occurred when launching Maemo Mapper immediately after booting the 770.

The dream:

Can I recover by deleting a file during the few minutes after a boot during which I can open an xterm and run a few commands? The question is "What file(s)?" I have been unable to figure out what file(s) to delete. (If only "du -sk" would work!)


What might I have done to cause the crash?
I can only guess. The only thing that I did that was odd before the previous crash was, during the previous Maemo Mapper session, to save the track (12-hr drive) to a file, clear the track, close Maemo Mapper (without turning off "Show Track" in the View menu). Then, I used bash commands to move the saved track file to another directory and turned of the 700. Later, when I booted the 770 and launched Maemo Mapper it crashed. I have no idea whether moving the track file might have caused the mapper to crash while starting.

Any suggestions for recovering without reflashing the 770 would be terrific.

I have a similar issue. I have 5 apps loaded in addition to the stock OS2006 flash load. I have GPE calendar, Gnumeric, Maemo Mapper, osso-xterm and system-monitor-plugin. Whenever the 770 reboots it show 3MB of internal flash available and crashes after a couple of minutes. If I reboot several times, and try to load apps until it crashes, it will eventually clean up the trash and show 37 MB free. My strategy is to never turn the 770 off. I just put the cover on to turn off the display. This way I go for days without having a reboot. Do you think it is Maemo Mapper that is causing this? I thougt about removing MM and seeing if the 770 acted differently on a reboot, but I'm reluctant to invest the time. Even more so now that Gnuite is planning on releasing MM2 this weekend.
