Also, I noticed it's leaking quite fast, and even before any RX errors are shown. So my previous guess w.r.t. cause and effect might have been wrong: [root@primerib linux-2.4.21-6.EL-olof]# netstat -i Kernel Interface table Iface MTU Met RX-OK RX-ERR RX-DRP RX-OVR TX-OK TX-ERR TX-DRP TX-OVR Flg eth1 1500 0 54793 0 0 0 67048 0 0 0 BMRU ~6240 PCI mappings had been allocated with the above statistics (eth1 is the problematic interface in our case). -Olof -- Olof Johansson Office: 4F005/905 pSeries Linux Development IBM Systems Group Email: olof@austin.ibm.com Phone: 512-838-9858 All opinions are my own and not those of IBM
