Hmm...

The FIONREAD ioctl fails without to set any errno value...
(the syslog_error function adds it to the log message if set).

It is is redefined on solaris (see common/com-syslog.c) to
use the streams I_NREAD ioctl instead of FIONREAD.


Please take a look in "man iostream" (if I remember right);
perhaps they have changed the behaviour of I_NREAD ??

The question is what this means on solaris9 that you are
using... on solaris7 & 8 this does not happen, except on
real socket errors.


It seems to me, solaris9 returns -1 on EOF?!
Or do you have noticed any transfer/connection aborts
when this message happens?

In the EOF case you can ignore the error, i.e. using
(additionaly to the patch):

syslog_write(T_DBG, "can't get num of bytes: %s %d=%s",

instead of the syslog_error call, so the socket simply
gets closed.

The patch I've sent you last time closes the socket if
FIONREAD/I_NREAD fails, but still displays it as error:

if( (cnt=ioctl(hls->sock, FIONREAD, &len)) < 0) {
	hls->ernr = errno;
	syslog_error("can't get num of bytes: %s %d=%s",
	     hls->ctyp, hls->sock, hls->peer);
	close(hls->sock);
	hls->sock = -1;
	return;
}
