Hello Xiaoqiang,
These messages occur because the IOC's windows OS process is exiting when
some of the ca server threads remain running. When the winsock facility is
abruptly terminated these threads receive error status returns from their
windows socket calls, and they therefore print diagnostic messages. You can
interpret these messages to be benign if they occur only when the windows
IOC is exiting. The differences between R3.14.12 and earlier releases might
have to do with subtle changes in the execution order of the various threads
as the windows process is abruptly removed from the system.
Nevertheless, we recognize that there is a root problem; currently the EPICS
IOC lacks an orderly shutdown. The new ca server definitely has an orderly
shutdown and we will arrange for this shutdown to be called in the future
when the IOC exits.
Sorry about the confusion,
Jeff

With sufficient thrust, pigs fly just fine. However, this is
not necessarily a good idea. It is hard to be sure where they
are going to land, and it could be dangerous sitting under them
as they fly overhead. -- RFC 1925
