If you want to provide a self-contained test case, possibly we could look
into it, but these fragmentary bits of what you're doing don't really
constitute an investigatable problem statement.

I will note that EXCEPTION blocks aren't terribly cheap, so if you're
reaching the "EXECUTE sql_insert" a lot of times that might have something
to do with it.
