Changes by:	rohara at sourceware.org	2007-02-14 16:23:47

Modified files:
	ccs/daemon     : cnx_mgr.c 

Log message:
	Ignore EPIPE error when sending response. This can happen is, for example,
	rgmanager makes a request, ccs receives/processes the request, but rgmanager
	dies before ccs can send the response. Also added retry if we catch EINTR
	during write.
