Forget it. I think I have the issue. Too many open files. Maybe of interest to others: I frequently saved a "preference" (current article) in the preferences, but this took ages as a whole XML tree needs to be created and written to flash. To speed things up I changed the implementation to a randome access file where I kept the handle(?) (java.io.File) around. I always closed the file after reading/writing, but never closed the File handle. What's new to me is that this produces lots of open files. I would have expected that this is not the case as I always close the actual RandomAccessFile. I was wrong it seems.
To find out about the files you need to know the pid of your app's process and then I ran this: adb -s emulator-5556 shell ls -l /proc/1160/fd Which then produces something like this: lrwx------ root root 2010-06-14 20:09 0 -> /dev/null lrwx------ root root 2010-06-14 20:09 1 -> /dev/null lrwx------ root root 2010-06-14 20:09 2 -> /dev/null l-wx------ root root 2010-06-14 20:09 3 -> /dev/log/main l-wx------ root root 2010-06-14 20:09 4 -> /dev/log/radio l-wx------ root root 2010-06-14 20:09 5 -> /dev/log/events lr-x------ root root 2010-06-14 20:09 6 -> /system/framework/core.jar lr-x------ root root 2010-06-14 20:09 7 -> /system/framework/ext.jar lr-x------ root root 2010-06-14 20:09 8 -> /system/framework/framework.jar lrwx------ root root 2010-06-14 20:09 9 -> /dev/ashmem lrwx------ root root 2010-06-14 20:09 10 -> socket:[41904] lr-x------ root root 2010-06-14 20:09 11 -> /system/framework/android.policy.jar lr-x------ root root 2010-06-14 20:09 12 -> /system/framework/services.jar lr-x------ root root 2010-06-14 20:09 13 -> /system/framework/framework.jar lr-x------ root root 2010-06-14 20:09 14 -> /system/fonts/DroidSans.ttf lr-x------ root root 2010-06-14 20:09 15 -> /system/framework/core.jar lr-x------ root root 2010-06-14 20:09 16 -> /dev/urandom lr-x------ root root 2010-06-14 20:09 17 -> /system/framework/framework-res.apk lr-x------ root root 2010-06-14 20:09 18 -> pipe:[41905] l-wx------ root root 2010-06-14 20:09 19 -> pipe:[41905] lrwx------ root root 2010-06-14 20:09 20 -> socket:[41908] lrwx------ root root 2010-06-14 20:09 21 -> /dev/binder lrwx------ root root 2010-06-14 20:09 22 -> /dev/ashmem lrwx------ root root 2010-06-14 20:09 23 -> /dev/ashmem lr-x------ root root 2010-06-14 20:09 24 -> /data/app/com.newsrob.apk lr-x------ root root 2010-06-14 20:09 25 -> /data/app/com.newsrob.apk lr-x------ root root 2010-06-14 20:09 26 -> /data/app/com.newsrob.apk lrwx------ root root 2010-06-14 20:09 27 -> /data/data/com.newsrob/databases/newsrob.db lrwx------ root root 2010-06-14 20:09 28 -> /system/fonts/DroidSansFallback.ttf lrwx------ root root 2010-06-14 20:09 29 -> /dev/ashmem lrwx------ root root 2010-06-14 20:09 30 -> /dev/ashmem lrwx------ root root 2010-06-14 20:10 31 -> /dev/ashmem lrwx------ root root 2010-06-14 20:09 33 -> /data/data/com.newsrob/databases/webview.db lr-x------ root root 2010-06-14 20:10 34 -> /system/fonts/DroidSans-Bold.ttf lrwx------ root root 2010-06-14 20:10 35 -> /dev/ashmem lrwx------ root root 2010-06-14 20:10 36 -> /dev/ashmem lrwx------ root root 2010-06-14 20:10 37 -> /data/data/com.newsrob/databases/webviewCache.db lrwx------ root root 2010-06-14 20:10 38 -> /dev/ashmem lrwx------ root root 2010-06-14 20:10 40 -> /dev/ashmem lrwx------ root root 2010-06-14 20:10 41 -> /dev/ashmem lrwx------ root root 2010-06-14 20:11 42 -> /dev/ashmem lrwx------ root root 2010-06-14 20:11 43 -> /dev/ashmem lrwx------ root root 2010-06-14 20:10 45 -> /dev/ashmem (The version with the bug had a couple of more lines pointing to my currentArticle file). Hope this helps somebody else also. No idea why this only happened to Desire/Incredibles.
