>Have you tried using newshound instead of grabber to see what happens? (I assume you meant News Rover? BTW, I just found out that Grabber has been renamed NewsGrabber, and it still happens with NewsGrabber 2.1.06.) I have tried a few and the only one that seems to do it is grabber. However, grabber does not seem to do it when talking to a real news server. So as I said, there is some sort of interaction, but I'm not exactly sure what that interaction is. Here's my syslog: Jun 6 15:40:39 piano nntpcache-client[3349]: client task awakening Jun 6 15:40:39 piano nntpcache-client[3349]: cpu1970.adsl.bellglobal.com connect from unknown@cpu1970.adsl.bellglobal.com (206.47.37.201) Jun 6 15:40:39 piano nntpcache-client[3349]: sockets.c:427: <- MODE READER Jun 6 15:40:39 piano nntpcache-client[3349]: sockets.c:427: <- GROUP alt.binaries.cd.image Jun 6 15:40:39 piano nntpcache-client[3350]: client task awakening Jun 6 15:40:39 piano nntpcache-client[3350]: cpu1970.adsl.bellglobal.com connect from unknown@cpu1970.adsl.bellglobal.com (206.47.37.201) Jun 6 15:40:40 piano nntpcache-client[3350]: sockets.c:427: <- MODE READER Jun 6 15:40:40 piano nntpcache-client[3350]: sockets.c:427: <- GROUP alt.binaries.cd.image Jun 6 15:40:40 piano nntpcache-client[3349]: sockets.c:427: <- XOVER 331520-345243 Jun 6 15:40:40 piano nntpcache-client[3350]: sockets.c:427: <- XHDR PATH 331520-345243 Jun 6 15:40:40 piano nntpcache-client[3350]: sockets.c:167: connected to NNTP server corp.supernews.com. as DEFAULT Jun 6 15:40:43 piano nntpcache-client[3350]: group.c:206: current newsgroup on server 'corp.supernews.com.' now 'alt.binaries.cd.image' Jun 6 15:40:43 piano nntpcache-client[3350]: sockets.c:463: => [corp.supernews.com.] XHDR PATH 331520-345243 So it looks like it is running 2 threads, one which asks for XOVER and the other asks for XHDR PATH. I tried each manually via telnet localhost nntp; the XOVER runs great, but the XHDR is very slow. I strongly suspect that all the other browsers I tried do not use XHDR. Does this give any ideas? Evan
