Don't think so. I'm pretty sure I've seen this under Slowaris and also
FreeBSD.

Its seems the IIS servers when under load reset connections. This happen a
lot with .asp it seems, probably because .asp is so horrible slow and used
in situations when it shouldn't be used.

I'm not sure if this is a valid thing for them to do (I looked at the HTTP
specs and can't find the bit that says if your a shit server running on a
shit OS your allowed to reset the connection where you loaded).

I have _never_ seen this with a non IIS server, but I haven't looked hard.
What I did do one day was capture all the time this happened and then go and
probe which WWW server they were using using a perl script.

Anyhow, an option to wait N*rand() where N E [1..5) seconds might be useful
for these cases.
