Except the phenomenon above sometimes we can build PDU session successfully. But the UPF log indicated [ERRO][UPF][Util] Pool is full, it may not belong to this pool.

The RAN seems to send 2 UplinkNASTransport. Is this a right procedure?

@calee It seems to be normal, coz sometimes when we established PDU session successfully, the two UPlinkMASTransport messages also existed. Here is the capture file of the successful procedure.
