Re: Random Network Drops on Realtek Interfaces (re)
It looks plain RTL8168C PCIe controller. Is there any odd messages reported by re(4) such as watchdog timeouts? If you disable MSI feature does it make any difference?(Add hw.re.msi_disable=1 to /boot/loader.conf to disable MSI.) Disabling MSI didnt solve the problem. Any other suggestions?

Re: Random Network Drops on Realtek Interfaces (re)
Hmm, not yet. When you lost network connection on re can you still see incoming traffics from other hosts with tcpdump? Also would you check available mbuf with netstat -m when you think re is not respond to any request? No incoming traffic found with tcpdump, just outgoing arp requests from the local machine. netstat -m output: 258/777/1035 mbufs in use (current/cache/total) 256/396/652/25600 mbuf clusters in use (current/cache/total/max) 256/384 mbuf+clusters out of packet secondary zone in use (current/cache) 0/35/35/12800 4k (page size) jumbo clusters in use (current/cache/total/max) 0/0/0/6400 9k jumbo clusters in use (current/cache/total/max) 0/0/0/3200 16k jumbo clusters in use (current/cache/total/max) 576K/1126K/1702K bytes allocated to network (current/cache/total) 0/0/0 requests for mbufs denied (mbufs/clusters/mbuf+clusters) 0/0/0 requests for jumbo clusters denied (4k/9k/16k) 0/0/0 sfbufs in use (current/peak/max) 0 requests for sfbufs denied 0 requests for sfbufs delayed 0 requests for I/O initiated by sendfile 0 calls to protocol drain routines -c ___ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to freebsd-stable-unsubscr...@freebsd.org
Re: Random Network Drops on Realtek Interfaces (re)
Suggestions were: #1) try arp -da. This does not fix the issue. I don't see any ARP for any other IPs other than the local. #2) speed/duplex settings. I tried forcing 100FD on the box and that didnt resolve the issue. When I did force 100 full-duplex on the switch, the box appeared as if it was reporting 100HD. Odd. By chace can you find any messages in dmesg reported by re(4)? dmesg output related to re(4) would be more helpful as RealTek controllers used to show same device ids. Here is my dmesg output for the re(4) devices: re0: RealTek 8168/8168B/8168C/8168CP/8168D/8168DP/8111B/8111C/8111CP/8111DP PCIe Gigabit Ethernet port 0xd800-0xd8ff mem 0xfeaff000-0xfeaf,0xfdef-0xfdef irq 16 at device 0.0 on pci2 re0: Using 1 MSI messages re0: Chip rev. 0x3c00 re0: MAC rev. 0x0040 miibus0: MII bus on re0 re0: Ethernet address: 00:30:48:b0:ec:84 re0: [FILTER] re1: RealTek 8168/8168B/8168C/8168CP/8168D/8168DP/8111B/8111C/8111CP/8111DP PCIe Gigabit Ethernet port 0xe800-0xe8ff mem 0xfebff000-0xfebf,0xfdff-0xfdff irq 17 at device 0.0 on pci3 re1: Using 1 MSI messages re1: Chip rev. 0x3c00 re1: MAC rev. 0x0040 miibus1: MII bus on re1 re1: Ethernet address: 00:30:48:b0:ec:85 re1: [FILTER] Currently, I am not using re1. Only re0 for access. Another side note, I have updated the BIOS to 1.0a from Supermicro as of yesterday, but that has not fixed this issue.

Random Network Drops on Realtek Interfaces (re)
All, I've been experiencing an intermittent issue with a drop in networking connectivity on a couple of boxes. At random times I drop connectivity between the servers and their gateway. I am able to login via the secondary interface and /etc/netstart and everything starts behaving as normal. My switch shows the link is up, ifconfig shows the link is up, but I am unable to ping my gateway until running /etc/netstart. Somedays it'll happen a few times an hour, some days once every 8-10 hours. It really is intermittent, and driving me crazy trying to track down the issue. I've tried different cables, switches, gateways, IPs, and locations. Memtest for 5 days showed no errors. However, the same problem exists on two separate installs at different times. I am able to connect to the one server from the second via their secondary interfaces, so the problem isn't related to both network interfaces. Both servers have the Supermicro X7SLM-L motherboard, same CPU, RAM and disks. Using the Realtek network driver (re). pciconf shows: vendor = 'Realtek Semiconductor' device = 'Gigabit Ethernet NIC(NDIS 6.0) (RTL8168/8111)' class = network subclass = ethernet I've experienced the problem for some time now on both 7.2-RELEASE and 7.2-STABLE (09/20/09) using amd64. Any help or suggestions would be useful in getting to the bottom of this.
