Hi all!
Today I tried to start VOS instance I have around for testing a local
DBpedia that so far gave little problems and found I can't get virtuoso
to run. I already erased transaction files and so on but the problem
persists. The relevant part of virtuoso.log follows:

After that, succesive attemps to start virtuoso all end with
GPF: page.c:119 row length out of range
I figure out that since this is for the moment a test db I am doing
things with little care, like messing with indexes, installing VADs and
performing queries all at the same time, and the db still trying to make
checkpoints every now and then, which I think I don't need at all by the
moment because it's loaded once with DBpedia dumps and nothing more to
be added later (or little controled dumps, not several concurrent
writes). How do I dissable completely backup/checkpoints? I think it's
more important for me at this moment to be prepared for eventual crashes
and unexpected closings and shutdowns (that are to be expected while
still testing and learning how to manage this) and being able to go on
with testing on an usable db, that to worry about saving the latest
changes to db because after all it doesn't change that much now...
Any help about recovering this greatly appreciated, not that it would be
too much to start over with a fresh db and put dbpedia again but I would
like to save the day-and-a-half or so that it takes to load all the
thing again!
