Hi Tim,

The error might mean that (part of) your database got somehow corrupted.

To find out whether, and if so how/why,
could you check your server's merovingian log (assuming you start your server using monetdbd & monetdb)
or even share (the respective part of) it with us?

Also, which version/release of MonetDB are you using,
did you initially create your database with this or an older MonetDB, and
of which kind are your updates (updates, inserts, deletes)?

Thanks!
Stefan

Hello,

I have a database that I've been using for a while and which is updated
several times a day. Recently when trying to insert records, there is an
error:

 GDK reported error:
 BATsubselect: invalid argument: b must have a dense head.

Could someone explain what this means, and how/if there is a way to fix
the problem?

The command that produces the error is quite simple:

 INSERT INTO sometable VALUES (blah,blah,blah...);

and since it's part of an automated process I don't think anything has
changed. It was successful up to a two days ago.

Thanks!

Tim
