Dear Nick,

Thank you most kindly for your answer. However, I was merely asking
whether anyone else is experiencing the problem I was describing. I
can't imagine we are the only IX with a client announcing a great many
prefixes.

But since you mentioned it, are you aware that the specific problem is
addressed somehow in the upcoming 5.x version? If affirmative, may I
inquire what did you do?

Kind regards,
Athanasios
