similar to: ix? / Intel(R) PRO/10GbE

Hi list, since we activated 10gbe on ixgbe cards + jumbo frames(9k) on 9.0 and now on 9.1 we recognize that after a random period of time, sometimes a week, sometimes only a day, the system doesn't send any packets out. The phenomenon is that you can't login via ssh, nfs and istgt is not operative. Yet you can login on the console and execute commands. A clean shutdown isn't possible

hi, I have a hard time figuring this out, the kernel says: ... ix0: <Intel(R) PRO/10GbE PCI-Express Network Driver, Version - 2.5.15> port 0xecc0-0xecdf mem 0xd9e80000-0xd9efffff,0xd9ff8000-0xd9ffbfff irq 40 at device 0.0 on pci4 ix0: Using MSIX interrupts with 9 vectors ix0: Ethernet address: 90:e2:ba:29:c0:54 ix0: PCI Express Bus: Speed 5.0GT/s Width x8 ix1: <Intel(R) PRO/10GbE

Hi, I have a Dell T710 with 4 X 10G ethernet interfaces (2 X Dual port Intel 82599 cards). It is running FreeBSD RELENG_8 last updated on July 13. What I see is packet loss (0 - 40%) on IPv6 packets in vlans, when the machine is not the originator of the packets. Let me try to describe a little more. If a neigbouring machine ping6 it, there will be packet loss. If it act as a router for ipv6,

Monitoring a tcpdump between two systems, a FreeBSD 9.1 system has the following interface: msk0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500 options=c011b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,TSO4,VLAN_HWTSO,LINKSTATE> ether 00:11:2f:2a:c7:03 inet 10.0.1.199 netmask 0xffffff00 broadcast 10.0.1.255 inet6 fe80::211:2fff:fe2a:c703%msk0 prefixlen 64 scopeid

Guys, I've heard about some absurd RAM requirements for 9.1, has anybody tested it? e.g. http://forums.freebsd.org/showthread.php?t=36314 -- View this message in context: http://freebsd.1045724.n5.nabble.com/9-1-minimal-ram-requirements-tp5771583.html Sent from the freebsd-stable mailing list archive at Nabble.com.

Hi all, Over the last month or so I've installed FreeBSD 9 (-stable) on several Mac Minis via the memstick image; they seem to be pretty good little boxes for things like offsite secondary nameservers, for example, and they're easily replaced in case of problems. However, the newest minis have slightly different hardware, and FreeBSD can't find the built-in NIC. pciconf -lv on the

Hello, I need some advice how to debug this issue ... Recently I got a new mainboard for a router, it's a Gigabyte GA-H77N-WIFI with two onboard re(4) NICs. The problem is that re0 works fine and re1 doesn't: It doesn't receive any packets. Tcpdump displays all outgoing packets, but no incoming ones on re1. Ifconfig shows the link correctly (100 or 1000 Mbit, depending on where I

Hi In a dataset I have length and age for cod. The age, however, is ony given for 40-100% of the fish. What I need to do is to fill inn the NAs in a correct way, so that age has a value for each length. This is to be done for each sample seperately (there are 324 samples), meaning the NAs for sampleno 1 shall be calculated from the known values from sampleno 1. As for example length 55 cm

Hi, I'm trying to read a subset of a netcdf file into R, but although I'm relatively experienced using R, I'm still new to netCDF files, so this may be a very simple/stupid question! I've included an example of the type of file I'm looking at here. www.met.reading.ac.uk/~swp06hg/ccd1983_01-dk1_20.nc (~7Mb) It's a 2D array of the variable CCD along with its lat and

Hi there We have a pair of servers running FreeBSD 9.1-RC3 that act as transparent layer 7 loadbalancer (relayd) and pop/imap proxy (dovecot). Only one of them is active at a given time, it's a failover setup. From time to time the active one gets in a state in which the 'thread taskq' thread uses up 100% of one cpu on its own, like here: ---- PID USERNAME PRI NICE SIZE

Hello, I already consulted related lists @freebsd.org [1,2] but I have remained unsuccessful to solve the following issue: VPN works for an internal IPv4 subnet, but I doesn't for an internal IPv6 subnet with ULAs. To be honest, I don't have any experience setting up a local IPv6; so I guess that I'm doing something wrong here. For those that know FreeBSD: The main aim is to connect

Hello, The Xen community is working on a new virtualization mode (or maybe I should say an extension of HVM) to be able to run PV guests inside HVM containers without requiring a device-model (Qemu). One of the advantages of this new virtualization mode is that now it is much more easier to port guests to run under it (as compared to pure PV guests). Given that FreeBSD already supports

Hi Folks, Thanks to several people's suggestions and clarifications, I think I have implemented a function which computes the conditional mean and covariance matrix of a subset of the dimensions of an MV-normal variable, given the values on the other dimensions (these conditioning value can be presented as a matrix, to deal with several cases at once). The code is below, for anyone who would

Greetings, The following question has come up in an off-list discussion. Is it possible to construct a regular expression 'rex' out of two given regular expressions 'rex1' and 'rex2', such that a character string X matches 'rex' if and only if X matches 'rex1' AND X does not match 'rex2'? The desired end result can be achieved by logically combining

Dear R'sians, Would really appreciate if you could suggest a more efficient way to order the columns of a dataset. The column names of the dataset contain indices separated by a period. Following are examples of my code and the dataset. oC <- function(tg=x2) { lth <- length(grep("T",names(tg))) thix <-

I'd welcome some comments or advice regarding the situation described below. The following illustrates what seems to me to be an inconsistency in the behaviour of matrix subsetting: > Z<-matrix(c(1.1,2.1,3.1,1.2,2.2,3.2,1.3,2.3,3.3),nrow=3) > Z [,1] [,2] [,3] [1,] 1.1 1.2 1.3 [2,] 2.1 2.2 2.3 [3,] 3.1 3.2 3.3 > dim(Z) [1] 3 3 >

Dear all, What is the quickest and most efficient way to diff two data frames, so as to obtain a vector of indices (or logical) for rows/columns that differ in the two data frames? For example, > Xe <- head(mtcars) > Xf <- head(mtcars) > Xf[2:4,3:5] <- 55 > all.equal(Xe, Xf) [1] "Component 3: Mean relative difference: 0.6863118" [2] "Component 4: Mean relative

Ive been googling quite a bit now for problems with running out of mbuf clusters. Im basically sending a 30k datachunk down 1000-4000 connections, but 1000 is more than enough to quickly fill upp 8192 mbuf clusters. I also tried setting maximum amount of mbuf clusters to 65536, but that only made the box hard-wire 86MB of 96MB RAM, making it just as unsuable as a dead machine. Of course, when the

Andre, Are you going to have time to MFC things from -current for auto-tuning -stable before 9.2? I fear (maybe unnecessarily?) that we are about to ship yet another release that can't do basic 10gigE when sufficient memory exists. If you don't have time, then let me know and I'll see what I can do. -- Alfred Perlstein VP Software Engineering, iXsystems
