<div class=Section1>
<p class=MsoNormal>I am having an issue with WSM7 using TW 11.0.00dTG2. I can
make about 50-60k requests in the space of about a minute before I get timeouts
and connection failures. This is from a single host to a DSR vip with 3 IIS
hosts on the backside. If I run the same query against an individual server it
takes a bit longer, but I don’t get any failures. The configuration is
non-sticky and the queries are only about 15-20k each using apachebench on a
single url. When the serveriron starts reporting failed connections or a query
times out, I can still get to the real servers normally. Any ideas on why this
may be happening? Is there a default setting within 11.0.00dTG2 that would need
to be reset? I tried overriding by adding client TRL and other settings for per
user and for per server, but none actually seemed to help, so I reverted.. Here
is the config, can anyone spot something wrong?? One note, the application
actually returns a 403 when asking for “/”, so I want to make sure
those pass.. I did disable l7 after I added the 200 and 403 healthcheck
responses, so those are remnants are ignored..<o:p></o:p></p>
