Hi,

I'm running FreeBSD 2.2 with INN1.5.1 and am experiencing the following 
problems:

1. NNRP readers often get "cant read Connection reset by peer" errors 
2. my NNTP feeder frequently serves me with two or more simultaneous feeds, 
   when there is one active and the secondd kicks in, I get the following 
   error message (syslog trace), and the first one closes. (a few checkpoint
   messages are edited out for readability)

I've tracked error 2. down to the following piece of code in innd/chan.c,
but that doesn't help me much.

		    if (bp->Left) {
			cp->LastActive = Now.time;
			i = largewrite(fd, &bp->Data[bp->Used], bp->Left);
			if (i <= 0) {
			    oerrno = errno;
			    p = CHANname(cp);
			    errno = oerrno;
			    if (i < 0)
#  Here comes the error
				syslog(L_ERROR, "%s cant write %m", p);
			    else
				syslog(L_ERROR, "%s cant write", p);
			    cp->BadWrites++;
			    if (i < 0 && oerrno == EPIPE) {
				SITEchanclose(cp);
				CHANclose(cp, p);
			    }
			    else if (i < 0 && oerrno == EWOULDBLOCK) {
				WCHANremove(cp);
				CHANwritesleep(cp, p);
			    }
			    else if (cp->BadWrites >= BAD_IO_COUNT) {
				syslog(L_ERROR, "%s sleeping", p);
				WCHANremove(cp);
				SCHANadd(cp,
				    (time_t)(Now.time + PAUSE_RETRY_TIME),


Does anyone have an idea what may be causing this ?

Regards,

- Maartje.
