I think it is a thread/process issue as you suggest. Since each httpd runs
in its own process space under Unix, a socket "pool" doesn't make sense.
Each httpd process simply needs to initialize one re-useable socket, since
each individual process handles only one request at a time. The static
mod_jserv pool that you create is statically "shared" in a multi-threaded
app, but not shared at all under Unix. I have no clue what's causing the
errors exactly, but I'm guessing that the errors you're getting with
Solaris are a result of having to initialize a new socket for each request
in turn, resulting in a more obvious manifestation of any "boundary
conition" problems inherent in the patch. Then once sockets are present in
the unshared per-process scoreboards, there are no errors. The problem may
be present under NT, but you would notice it at most once, since after the
first request has been answered, the socket scoreboard has a socket
available for all subsequent requests. I think this analysis is consistent
with the fact that you find errors intermittently towards the beginning of
your test, but not towards the end of your test (under Solaris).
But then again, I'm not a certified apache hacker, so I might be completely
wrong :)
