GNU Smalltalk used in....

A good way to promote GST, could be to have some page, where we can  
put, the projects where GST is being used.

What do you think about?

Are there any? :-)

But seriously, we've never been so close to that.  Let's wait until
after VisualGST is merged.

Well, Why not? If it's stable, I'm thinking serously to use GST to my  
production needs, a POS system is one of them. Nico is working on a  
web framework too, for some reason I suppose.

I think, merged or not, is more important for me get it working on OSX  
first :D Oh, and I don't started to try it on Windows, and I suppose,  
will be other headache :P

Once the socket bugs are fixed, there will be at least one .-D

Hey, so far everything seems to look like a Swazoo bug, not GST. :-)

I wonder why nobody complains over in AIDA-land, where Swazoo
is used as basis, too. Am I the only one stress-testing his
web app? Not that I would call 25 users a real stress test.

OTOH, it might really be a somewhat unusual request pattern
compared to what I imagine normal business usage to be.

Well, 25 simultaneous cold-cache accesses are pretty heavy, especially
if you consider that most production setups will use a load balancer.

The root cause of the CLOSE_WAIT bug is definitely there in upstream
Swazoo.  You had 1000 open sockets, presumably because of keep-alive
behavior of Swazoo (I'll research what apache or lighttpd do) which is
of course nothing that GST cares about---it would be different if say
you were missing close system calls, but nothing seems to hint at a bug
like that.  Third, the fact that the accept error message repeats over
and over is there in upstream Swazoo too, and it's trivial to show it:
if you don't have some kind of exponential back-off after an EMFILE
error, you're going to get hte same error over and over again.

But this is very comforting for me, because it shows we're doing things
seriously.  Thanks.

Paolo

Just imagine ... all of this would not have happened, if I had
managed to get my apache config right ... we'd have stayed below
the critical threshold like all the others :-)

manage their own socket pools?

What is comforting for me is that there are smart guys out there
who tell me a) that it was not my fault and b) that it can be fixed :-)

No, they simply throttle down the pretenses of the client WRT
keep-alive.  Swazoo does not have any protection against DoS.

That's the truth: you DoS-ed yourself. :-)
