Event ID 1078

Hello!

We have a web farm with 12 web servers, and we store the state on a state
server.

Occasionally we get error (1078) in the event log on the state server.

---
The state server has closed an expired TCP/IP connection. The IP address of
the client is 10.99.194.151. The expired Read operation began at 11/06/2005
21:51:23.
---

I have read about the error here:
http://support.microsoft.com/default...b;en-us;308097

But the problem is that none of our webserver or the state server is near
100% of cpu. The state server avg 10-15% and the web servers avarage between
10-20%. And they never peak higher than 40%.

The problem is reported to the event log ~20 times per minute.
Sometimes the error can go away for a couple of hours or a whole day, and
then the problem can come back for a couple of hours/days.

When the problem is reported it is mainly reported by one web server. But
over time all the webservers have had the problem.

How can I investigate this further?

Why not just try the resolution mentioned in the technote to increase the
timeout from 10 seconds upwards. Alternatively or in addiation, what about
upgrading the servers processor, memory etc and / or reducing its load by
turning off non essential services.

As I wrote we dont have any performance issues with our servers. So I cant
see why I should add more memory. Our webservers only handles asp.net, and
that is the only thing it does so we annot turn off any more services.

I cant see why I should increase the value since - once again - our servers
cpu peak is not near 100%. And it says that the timeout already is 10
seconds. If we have a bottleneck somewhere that makes it take 10 seconds to
do something, then we need to fix that. But the thing is that even during our
peak hours our site responds fast.

Other suggestions?

Perhaps it is the concurrency of the requests which is causing a denial of
service. I dont know enough about this to really give you an accurate
answer. If your servers are not running anywhere near 100% ( Which I misread
to be near 100% Hence my post ) then perhaps it cant cope with the number of
concurrent incomming connections and denies service.

Its a stab in the dark, but why dont you take a look at that metric and see
if it yeilds any further cause for investigation.

Hi Patrik,

Since you mentioned that both the webserver and stateserver both run with
low CPU utlization, I think the configuration is proper for common requests
in your secnario. However , there may exist some certain session processing
which cause the stateserver timeout that connection. Is there any large
memory exchange with the SessionState in your applicaion? For such problem
in production environment, it would be better if we can try isolating the
problem to a small scope, maybe page level or ...

Thanks,

Steven Cheng
