This is normal. The request was forwarded to the remote host and the
processing is done for now. In other words, IGNORE means that no reply
should be sent now even if the AuthBy has done its job.

Later when the reply is received from the next hop, it is returned back
to the original sender. The processing happens asynchronously in two
parts: forward first, do something else meanwhile and then send back the
reply when the next hop replies.

Hmm, it might be the next hop replied too late or this was a duplicate
reply for some reason.

If it seems the next hop servers are having problems processing all
requests, you could consider taking a look at their logs.

Another idea might be to have separate instances that handle accounting.
This allows you to split the load and usually this helps to keep the
configuration files more simple since you do not need to handle both
accounting and authentication with the same configuration.

However, it might be worth taking a look at the next hop performance first.

Thanks,
