Anyone has a clue where and why those error messages comes from?

Could you try ab -k? - mod_proxy will reuse the socket -



Still the same messages.
When running ab on the same host where apache and TC are located I'm getting
between 3-16 errors on '-n 1000',

Don't run ab on the same host, otherwise you are benching ab.

But when using remote machine and use the ab from remote I'm getting around
50% error requests; cca. 450 - 520 requests gets failed.
The number of failed requests gets lower and lower when I run same ab in a
series, and it get more and more random, varying from 0 - 50 %.
Interesting is that rising concurrency level to 20 or more, lowers the error
number, but It's still around 10% (1120 from 10000 request are 502).

I also I have some (40) errors with concurrency 300 but Tomcat and Apache are in 2 different machines:

Very strange and totally unusable at least on WIN32.

Use a real operating system.
