The following reply was made to PR kern/3925; it has been noted by GNATS. From: Bill Fenner <fenner@parc.xerox.com> To: freebsd-gnats-submit@freebsd.org, peter@spinner.dialix.com.au Cc: Subject: Re: kern/3925: SO_SNDLOWAT of 0 causes kernel to use 99% of CPU time on TCP send Date: Sun, 22 Jun 1997 10:05:35 PDT soreserve() is usually only called when creating a new socket. Sanity-checking 0 is clearly acceptable when doing the setsockopt(). Since soreserve() silently "fixes" it, perhaps setsockopt() should too. I don't know what to think about sanity-checking in other situations. Bill
