KR-09. Bad handle passed to system.
KR-13. Cannot allocate required local memory.
KR-21. Error restoring state. Please exit and restart the system.
Since you're not losing data, the error messages are not a serious problem.
It's unlikely that they are due to bad hardware, though it's possible, so
there's no harm in replacing the unit.
Perhaps your ramdisk is low on free space... Ideally, you'd get a message
saying so, instead of the more cryptic messages that you're getting. But it's
one possibility. When you reboot the device, the state files are deleted,
freeing up more of the ramdisk, and thereby avoiding problems until it runs
low on space again.
Do the errors happen only in a specific application or only with a particular
document file? If so, it's possible that the document file is corrupt.
