We have seen these occasionally in the past, but they are becoming more frequent. The majority of transactions have no problems.
 In the PDT Payment Gateway notification, $_GET shows result = success, st = completed, ; $_POST shows status = 400, error = Bad Request

What can we do to figure out the problem?

Have you reviewed the raw data in the notification? It should be at the bottom. If PayPal sent back an error it would be there. Please also check CBSubs > History Log to see if any errors were logged.

Yes, the above is an extract of it, which I don't know how to interpret. The fields in $_GET seem to indicate success, but those in $_POST show a 400 error.

That error means the HTTP call to PayPal's server itself failed. Either PayPal rejected it, the outbound request was blocked by your server, or PayPal server was potentially down momentarily. There unfortunately isn't anything we can do about this. If you've a firewall configured on your server be sure it has open ports for PayPal and doesn't block PayPal IP Addresses.

The best I can suggest when this happens is to manually mark the basket paid in CBSubs > Baskets after you've verified the payment went through fine. This assumes the IPN didn't come through and pay the basket though.
