> the querys are executed in a copy of that db. On tuesday, i recognized the issue (that came without any reason). After a gbak, i stopped programs that were using the database, stopped the default instance and made a copy to a different volume, so i have a database i can Analyse. Currently, i made another copy, that i use to Analyse it with IBFirstAid 2.6.

I wonder if index RDB$INDEX_20 is corrupt. What's the result of:

select
rdb$collation_name || ''
from
rdb$collations
group by
rdb$collation_name || ''
having
count(*) > 1
