-151 ERR CNCT CLOSED BY REQ (Magic xpa 4.x)
During the execution of a request, the requester closed the connection after receiving status -110 (REQUESTER_TIMEOUT).
As a result, no output was sent back from the enterprise server to the requester. Check the requester in the client machine and the enterprise server. If possible, reproduce the problem by setting the Log parameter to Enabled in the Mgreq.ini file (log = Requester.log Y R) in the directories of the requester and the enterprise server.
This is an internal status code, closely coupled with status -110, and should be handled on the client side.
