Re: InstantDB: Cols error ??


Martin

I vaguely remember adding a fix for something like this. If I remember rightly, IDB used
to do some consistency checks on string during recovery, but if it found a problem it just
stopped - as you described.

I think the latest version logs the problem and continues. So it might be worth trying a
more up to date IDB version to see if it can get around the problem.
