Every so often, (quite often actually) I'm getting this internal
exception when I use the JDO PersistenceManager (or at least I think
that is the case).

It does not happen all the time. Can somebody explain to me what the
root cause is for that. I'm iterating through the results, but it
seems that this is causing this issue (once in a while)
