I did not find any docu about that. Why qos set this to 256? if someone have only 25, because did not have more ram … qos set this to 256! And i have 300 … and qos set this to 256 … i dont understand that.
one other question: it is possible to build slowloris with very slow downloads … perhaps that should be checked to. if download is less then x bytes, kill it.

OK, after reading more, i find out, that not the official docu say anything about ServerLimit, i got this from every howto.
# maximum number of active TCP connections is limited to 256
ServerLimit 256
True? Is this limited by qos?

one more thing: it is very bad, that qos is displayed in the extended server-status … without to change that! We have ~7.ooo Vhosts and currently we cannot use this anymore :-/

mod_qos does not apply any limitation to the ServerLimit directive. Find more about this at http://httpd.apache.org/docs/2.2/mod/mpm_common.html#serverlimit.
The next release of mod_qos (9.7) may be compiled defining QS_NO_STATUS_HOOK which prevents mod_qos from registering to mod_status.
