FreeBSD horus.cpc.wmin.ac.uk 2.2.6-RELEASE FreeBSD 2.2.6-RELEASE #0: Wed Jun 24 09:47:42 BST 1998     root@horus.cpc.wmin.ac.uk:/usr/src/sys/compile/HORUS  i386
>Description:
I am using a FreeBSD machine (horus) as a router which provides
network access to another FreeBSD machine (ptah). The problem is
that when I download a large file (800KB) using netscape and store
the file onto a NFS mounted disk, then the router (horus) reports:
"no buffer space available". I then need to do ifconfig ep0 down & up
again to resume the situation. I tried to increase the NMBCLSUTERS to 4096
but it is still the same. Please note that the router does not report
any error messages when the file is downloaded onto the local disk.

The two ethernet cards in the router are a SMC8013 and a 3Com 3C509.
The latter card is used to provide network access to the other PC which uses
a 3COM 3C590 Etherlink III PCI (vx0).

 I believe there is an mbuf leak in the ep driver which
 is probably the reason you are running out of buffers.

 Hi Paul,
 
 Thanks.
 
 I replaced the Ethernet card with a WD8013 and it works fine.
 
 Thierry.
