Re: Pbxt loses rows


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.

This is a bug that has been around a long time but not yet fixed (at
least not in 1.0.11 which is in the MariaDB 5.1 tree).

Once in a while when running the pbxt.insert test, pbxt fails to find
all rows in the table:

pbxt.insert                              [ fail ]

Rerunning the test usually works

It would be really good to get this fixes ASAP as it's not good if a
storage engines looses rows randomly...

The above happend in my latest 5.1 tree on Linux.
