Subject RE: Network is unreachable: connect to listener
Date Wed, 10 Jul 2002 02:01:19 GMT

I haven't exceed the maxclients setting.  My setting is 256, but the
concurrent thread of ab is only 100.  My Listen directive doesn't
specify the interface.  I just specify the port.  And there are two
Listen directives(80 and 8080).

But may be it's really the cause of maxclients.  As I have also tried to
use worker mpm of apache.  Concurrent thread of 100 doesn't generate
"Network is unreachable" in this case.

I have another question.  I have a web application which has a great
number of hit.  I have already use DNS round robin to have two apache in
two different servers.  However, there is still HTTP request timeout.
There are about 1500 hit in 30 seconds.  The hit is in arbitrary
interval.  I want to test whether worker or perfork mpm is suitable in
this scenario.  However, whenever I use ab with the concurrent thread
greater than about 150, the performance drops at a great extent.  I
really don't know where the bottleneck is.  And Indeed the performance
is quite similar(or the same) for the two mpm.

Thx. and Regards.
Steve.

Did you exceed your maxclients during your test? Do you have a
Listen directive pointing to something other than the default
or an appropriately configured and working interface?
