This is not a bug report :-)

A SunOs listen queue question...

Is there a document anywhere that describes how to change
SOMAXCONN under SunOs?

We changed the define in /usr/sys/sys/socket.h and recompiled
the kernel, but it didn't seem to have an affect. The sys-admin
did a grep for that string in the sources that he had and it didn't
appear to be referenced anywhere.

Someone else said that it might be possible to edit the kernel
binary to up the number, but that sounds dangerous as it isn't
obvious if resources are allocated at compile time or dynamically.

Anyone have any info on this?

Hmm, I'll have to pass on this one; but if I recall correctly there
was a problem with that; for some reason SOMAXCONN does *not* correspond
with the real SOMAXCONN as they appeared to have different names.

Check out that page from the guy of the virtual museum paris, he
had a lengthy tract on it; He is called Stefane Borzmeyer or something.
http://www.cnam.fr/personnes/bortzmeyer??? There is also a sun paper on
it; but my port-80 connections are down for the next few hours.
