I suspect that this is not due to rows being lost, but rather to the
rows not being found for some timing reason.
But, of course, only debugging will tell...
We have scheduled time to look at this error.

Hi Monty,
Unfortunately I have no idea what this problem is, except that I have
never seen it in the insert test before.
Has the insert test been modified recently?
I guess it is more likely that the select is delivering a different
number of rows than the INSERT failing.

Hi All,
Yes, PBXT uses a lot of file handles: generally 3 per table. It opens
all tables before recovery. Unfortunately, I have not worked on
optimizing this behavior.
Although the only reason for this is to resolve possible FK/PK
relationships. So I think this should be considered a PBXT
