            Description

            If a ForwardClose request is currently processed and the underlying messaging connection closes in the meantime (TCP FIN or RST), the stack-internal resource used for this explicit (UCMM) request will  not be freed but remain occupied forever due to software bug. If all of the 8 available resource objects have leaked away, the device will reject all further requests at the ENIP-layer with eror code 0x2 (EIP_ENCAP_NO_MEMORY).

            The issue has been fixed.
