Spurious RST, segment rejected - possible pattern?

Hi all,

While conducting some benchmarks against various webserver software, 
(7-CURRENT client vs 7-CURRENT server), I couldn't help notice that the 
flood of Spurious RST (which only happens on the server side) seems to 
follow a specific pattern.

#a HTTP Server: 192.168.0.100 (FreeBSD 7.0-CURRENT #3: Tue Jul 24 
15:31:44 WEST 2007)
#b HTTP Benchmarker: 192.168.0.1 (FreeBSD 7.0-CURRENT #3: Sun Jun 10 
12:43:23 WEST 2007)

* by "FAILS", I mean the expected result is too low, compared to a 
session where no "Spurious RST's" happened. OK means no such messages 
were seen.

Here's how it goes:
* webserver restarted _at_ #a
* benchmark runs and FAILS _at_ #b

* webserver restarted _at_ #a
* benchmark runs OK _at_ #b

(etc etc)

On the client machine, there are no such errors. I only get spurious 
RST's on my workstation when using ktorrent. Normal 
browsing/email/downloads via opera never seem to trigger it.

Notice the source ports number are always the same on each run, perhaps 
that's valuable information for someone who deeply understands the 
code.. if any of the above was helpful, let me know if there's anything 
else I can do.

Best regards,

Hugo
