Hi Daniel -
Thanks for looking into this.
When you say, this patch applied to 1.1, do you mean we
still need to get this patch (if we already have 1.1)?
In any case, we are in the process of getting this patch.
However, what I dont understand is - how can the
configuration be incorrect as this happens
only "intermittently".
So, in my load test case, I have a load test application
that runs against a web service. When the number of
simultaneous connections go over 20-25 range to the web
service, we begin to see these errors.
In my case the scenario is as follows:
Two separate machines:
1. Web Services Client (for load testing):
A simple .net console app (.NET 1.1 Framework)
2. Web Services Server:
A .Net web service hosted on IIS 6.0 (on Win2K3)
on .NET 1.1 Framework.
I start to see these errors when the load goes
beyond a certain threshold (about 25 connections, I
believe are open at that point).
What I have experimented with so far:
- Cleared the keep-alive flag on the IIS and on the
client by overriding the client proxy methods
- IIS 6.0 is configured to receive unlimited connections
and configured to have really long timeouts
If the configuration was incorrect, I would expect that
this would fail each time, but it fails with these errors
only under load.
Thanks in advance.
