Description:	When a manager sends a Logoff command and immediately disconnects without waiting, the following error is sometimes logged (but not always). ERROR: utils.c: ast_careful_fwrite: fwrite() returned error: Broken pipe The error reproduces reliably by calling shutdown(.., SHUT_RD) on the manager's end of the socket before sending a command. I have a local fix, sending a patch.
