Default Re: callback unknown error

I have paypal express checkout enabled through xcart, and payflow for credit cards through x-payments.

Now when I look at the IPN history in paypal, the orders not being sent are only credit card payments.
Is it correct to use the "xcart/payment/ps_paypal_ipn.php" location for ipn url?
Will it cause problems for x-payments?
Im going to add that there does not seem to be any actual problem that I am aware of. Just these error messages.
