When it resets, the same book/pages can be read and, immediately after a clean start, the memory's available...

(There have been cases reported in the past where it's been possible to create ePub's which always crash the reader, but AIUI, those cases have been found & trapped.)
I've had my 505 spontaneously re-boot perhaps a dozen times in just under a year, with daily usage. The common factor seems to be the accumulation of a large number of bookmarks and a lengthy reading history, at which point I suspect a memory refresh is required. I've found that bookmarks are not usually lost, but reading history is. Leaving the reader to snooze or explicitly turning it off does not seem to affect the frequency of occurrence.
