 Three weeks ago, I, and a few other INN administrators, posted about
 FreeBSD -STABLE's inability to run the newest INN code, due to MMAP() race
 conditions...essentially, after X hours of run time, on a heavily loaded
 INN server, the whole thing locks up solid.
 
 At that time, Matt pop'd up and stated that he knew of *at least* 6 MMAP()
 related race conditions that he was hoping to be able to get fixed "within
 a week"...that would have been two weeks ago.

Maybe I missed that (I'm only on -stable, not -current), but what's the
current situation concerning this issue?

Can I dare running the newest INN on -STABLE / -CURRENT or do you still
experience these problems?

If it makes you feel any better, I'm in exactly the same position
and losing my battle because of NFS and SMP issues. We just got two more
intel boxes to work with on this project, one is already set up for linux
(making a total of two), when I asked my boss about the other one he said
he's not sure yet what he wants to do with it. 

There was a similar thread to this one instigated by me a few
weeks ago. I got the same, "well run stuff that runs good on freebsd
instead" response. My problem is that my project parameters are set by my
boss (and reality) and require smp and nfs that work at least as well as
linux'. They don't, so I'm losing my battle.

1999-07-08 Thread The Hermit Hacker


I wish to make one thing perfectly clear here, or, rather, a couple of
things.  None of this thread was started as a 'slam session' against
*anyone* out there...

To those that have responded privately that "they are experiencing the
problem too", without a better way of saying it...that helps absolutely
noone.  If you are experiencing the same problem, voice it to the list.
Right now, there are only a few of us that I know of, and, compared to the
"grand scheme of things", that isn't even a pebble on a beach.

Personally, I'm at a disadvantage to debug this, as my baby is 2.5k
kilometers away from me :(  She's on a serial console, through a
portmaster, that doesn't appear to have any way of allow me to break into
DDB...but, even so, I'm spending as much time as possible following
directions from those that appear to want to do more then just tell me to
run Linux for an INN server *sigh* 

A few weeks ago, one admin posted a quick C program that, if you ran and
ctl-c'd from it several times, would cause the machine to hang...can
someone resend that out?  I'll use it on my machine at home to test
4.0-CURRENT, and I have a machine at the offiec running 3.2-STABLE to test
on...
