Yes, an example (full table):
Srv PID Acc M CPU SS Req Conn Child Slot Client
VHost Request
0-0 13755 49/49/49 W 0.10 0 0 119.0 0.12 0.12
gatec-mgt.kw.bbc.co.uk webapp0-mgt.mh.bbc.co.uk GET /status/ HTTP/1.0
and after the next request:
Srv PID Acc M CPU SS Req Conn Child Slot Client
VHost Request
0-0 13755 0/53/53 W 0.14 0 0 0.0 0.12 0.12
192.168.200.12 webapp0-mgt.mh.bbc.co.uk GET /status/ HTTP/1.0

No it changes (at least it looks so).

I'm using the worker mpm.

Yes e.g. with:
ServerLimit 1
StartServers 1
MaxClients 1
MinSpareThreads 1
MaxSpareThreads 1
ThreadsPerChild 1
MaxRequestsPerChild 10000
I get one entry only.
While with:
ServerLimit 1
StartServers 1
MaxClients 5
MinSpareThreads 5
MaxSpareThreads 5
ThreadsPerChild 5
MaxRequestsPerChild 10000
I get two (didn't manage to get more than two).
e.g:
Srv PID Acc M CPU SS Req Conn Child Slot Client
VHost Request
0-0 14288 20/70/70 K 0.18 4 0 8.1 0.20 0.20
192.168.200.12 webapp0-mgt.mh.bbc.co.uk GET /images/sra.gif HTTP/1.0
0-0 14288 7/8/8 W 0.18 0 0 4.4 0.00 0.00
192.168.200.12 webapp0-mgt.mh.bbc.co.uk GET /status/ HTTP/1.0
With:
ServerLimit 5
StartServers 5
MaxClients 5
MinSpareThreads 1
MaxSpareThreads 1
ThreadsPerChild 1
MaxRequestsPerChild 1
and enough concurrent requests I get to see a max of 5 requests.
I've been just testing with older apache 2 versions (down to 2.0.46) and
it seems all behave the same (looks like I only noticed just now).
I'm probably going to attach a debugger but it would be good to know where
to start poking.
The second thing I'm going to try is compiling with gcc .
Hope that helps a bit,
Andre'
