I would have expected that it was on the client, but changed my mind when I noticed that if it were reporting out of memory on the tcp sendmsg it should also have logged "Error 12 sending data on socket to server" (so there are only a few other places where out of memory is logged, such as allocating the small amount of memory for a mid entry - but that would not be an issue if there were fewer than five or six SMB/CIFS requests active from the client at that time). ERRNOMEM (rc=12) is also returned when the server says it is out of resources (or out of memory or short on paging space)
