yes it did.  Look at the limit/ulimit shell builtin, here is mine:

$ [marc at laptop ~]$ ulimit -a
core file size          (blocks, -c) unlimited
data seg size           (kbytes, -d) 524288
file size               (blocks, -f) unlimited
max locked memory       (kbytes, -l) unlimited
max memory size         (kbytes, -m) unlimited
open files                      (-n) 7264
pipe size            (512 bytes, -p) 1
stack size              (kbytes, -s) 65536
cpu time               (seconds, -t) unlimited
max user processes              (-u) 3632
virtual memory          (kbytes, -v) unlimited
[marc at laptop ~]$

it looks like the data segment size needs to get bigger.  You should
also talk to the backula people about chunking the output instead of
getting it all at once.

you asked a vauge question, with no supporting info, and it looks like
you spent less then a minute typing it.  If that is how much you value
our responce why should we make one?  This list has, by its nature, a
good deal of delay between messages.  And by not puting a bit of
effort and info into what you send you are implying that we need to
figure out your problem and that implys that all of our time is not as
valuble as yours or to put it another way you are being very rude. 
While at the bar after a meeting it would be fine to ask that kind of
question, because the other person could clarify it quickly and you
are not shouting it to the whole group at the bar to list two reasons.

you seem to have missed a point or n here:
1: this list is not about giving you answers
2: there is no one here who must read your email
3: you will generally recive help in direct proportion to the effort
that is percieved to go into  the request
4: This list is here to discuss things by giving us more to talk about
you are more likely to get answers

thats good but you did not give us even a hint of all that work so how
were we suposed to figure it out.  This goes back to spending 10 min
to put together a good message, part of that is explaining to us we
are not the first stop on this issue.  also the info may help us
trouble shoot the problem or the act of writing it down may give you
new insight to the problem.

no hard work is the proper puchline to that joke.

what this 'we' stuff, again burn it into you thought process we are
not here to help you.  We may if we decied to, but that is up to us. 
If you keep implying that you should get free consulting you will get
exactly what you pay for.

This is a discussion list.  Its purpose is to discuss things, bsd
related or of general interest to the group.  Your problems may or may
not be of general interest to the group.  The fact that you are
posting questions in such a way that it looks like you are doing no
work on them befor bothering us with them is of general interest to
the group, this is because it tags you as someone to ignore in the
future and the present.  You are working hard to turn on the bozo-bit
and it is hard to turn off

it depends, this is not a newbees list nor is it a place for people
who apear to want to stay newbees.

You can ask all the stupid and ill concieved questions you want, but
after a while who will  bother to answer them.

you are asking questions in a format that shows a lack of respect for
the rest of us.  Since you want answers to them, to help you do your
job, you might want to change that behavior.  Since you are asking
questions it would be best for you to accomadate us, if you want

You seem to have missed the point.  It is not the questions I object
to it is the lack of work you put into writting them that I object to.

And this prevents you from spending 15 minutes composing a good
question so people would be inclined to help you how?

As far as the inner workings of your mind go I do not care.

You seem to forget I have tried to help you previously.  And the
message that you are replying to is an attempt to help you.  And the
way open source lists work, except the newbees lists, are generally as

You live and die by your reputation on the list.  If you generate a
reputation as a lazy idiot people will not help you.  Wether you are a
lazy idiot is a diferent question, but you are judged by what goes on
in the list.

we tend to meet any new situation by reorganizing, and a wonderful method it
can be for creating the illusion of progress, while producing confusion,
inefficiency and demoralization."
