System: NetBSD polaris.garbled.net 4.0_BETA2 NetBSD 4.0_BETA2 (GENERIC) #14: Sun Mar 25 01:26:44 MST 2007 root@polaris.garbled.net:/usr/src/obj/i386/sys/arch/i386/compile/GENERIC i386
Architecture: i386

>Description:
When attempting to fetch the file:
http://apt.uctp.net/wbel/4/en/updates/i386/xorg-x11-Mesa-libGL-6.8.2-1.EL.13.37.5.WB1.i386.rpm
via ftp or wget, the transmission stalls out partway through.   This is 
confirmed by multiple people on 4.0, multiple arches.  Works fine in -current.

tcpdump output:
