Solve the problem of 100% CPU PostgreSQL after service startup _postgresql

There are n Postgres.exe in the process (this is normal, see the official document), but there is always a full CPU (because this machine is dual-core, occupies 50% of the resources). The Pgadmin III connection will die out.

The problem did not find an answer on the web search.

Viewing the log found an error message:

%t log:could not receive data from Client:an operation being attempted on something ' not ' a socket.

According to the error, found the answer on HP's website (should be the question of win, but found the answer here, very interesting) (http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00724449& LC=ZH-HANS&DLC=ZH&CC=TW&PRODUCT=86191&LANG=ZH):
