still mbuf leak in 9.0 / 9.1?
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

Logic with regexps
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

efficiently diff two data frames
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)

Re-order columns
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.

lth <- length(grep("T",names(tg)))

Subsetting a matrix
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

Calculate NAs from known data: how to?
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

Lat Lon NetCDF subset
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.

Multivariate regression method
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

thread taskq / unp_gc() using 100% cpu and stalling unix socket IPC
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:

Salvage or undelete files of damaged ext2/ext3 file systems
Hi!
I have made some extensions to debugfs to undelete or recover files
from a damaged ext3 file system.
Salvage or undelete files of damaged ext2/ext3 file systems
debugfs salvage command can be used to salvage files from a damaged ext3
or ext2 file system. The code is alpha, so use at your own risk.
the usage is:

please test: Secure ports tree updating
CVSup is slow, insecure, and a memory hog. However, until now
it's been the only option for keeping an up-to-date ports tree,
and (thanks to all of the recent work on vuxml and portaudit)
it has become quite obvious that keeping an up-to-date ports
tree is very important.
To provide a secure, lightweight, and fast alternative to CVSup,
I've written portsnap. As the name suggests, this

Looking for driver help
I sent an email out to freebsd-net without a response, soo this is my last
attempt at getting any assistance here.

Integrated RTL8168/8111 NIC not assigned interface
I'm running 7.0-RELEASE-i386 on Jetway's NC92-N230 mainboard. The board has
one integrated RTL8168/8111 gigabit NIC as well as an expansion board with
three RTL8168/8111 NICs. Why would the three NICs work while the onboard NIC
does not?

em interface slow down on 8.0R
Hi,
I noticed that network connection of one of my boxes got
significantly slow just after upgrading it to 8.0R. The box has an
em0 (82547EI) and worked fine with 7.2R.
The symptoms are:
- A ping to a host on the same LAN takes 990ms RTT, it reduces
gradually to around 1ms, and then it returns to around 1s. The
rate was about 2ms/ping.
- The response is quite slow, but no packet
