I deleted and recreated the directories recommended by GeekPeter and now when new or existing messages are received the content cannot be read. I did do a full device restart after making the directories, etc..
OK, an extra reboot seemed to do the trick, so message content is once again readable.
By the way, I do a scheduled reboot every night at 3:00AM which I think helps with memory management and file garbage cleanup to some degree, perhaps delaying the appearance of the bug. Also, I have promised myself that if I ever get the offer to restart the device from the diagnostic message about the App DB being full, to instead just close the program and do a regular device restart. I had to rebuild the Pre3 about 6-months ago and have no desire to waste another day or 2 doing it again.
Based on the evidence from this thread I am suspecting the HP profile as a contributing cause of this problem. It is obviously something that persists beyond a reset of the device. Perhaps a combination of the profile and storage space limits.
There is definitely a need for a garbage collection/cleanup App and an easy way to manage partition sizes. For instance, I think that deleting messages does not remove all entries associated with the old message, particularly when the messages are removed because only 1 or 3 days are kept on the device at a time.
Such an App developer would get a significant donation from me and the thanks of many. Any takers?
