NAT6013 Unexpected bufferpool error

Hi I am getting a NAT6013 Unexpected bufferpool error. This message is accompanied by an error 82 on a line in a logon to broker subprogram and NAT6972 Directory error on Client, reason 05.

Any ideas how to resolve this???

The natural help says:

I don’t know this error but I would check the parameter AUTORPC and would try to ignore the Bufferpool by setting the Natural-Parameter BPSFI to OFF…
