| Are there any messages in the Jaugar log that indicate you may have
reach a maximum number of connections.
For example:
SRVLIB Message: 16133/10/0: Configuration of 100 connections has been
exceeded, connection rejected
How many clients are you running through your testing tool? From you
discription I am guessing you are doing some sort of ramp test since
after 3-4 hours you are seeing a problem.
Depending on the number of images you might have on a page you have to
take into account that a single client request can open multiple
connections at the same time, thats the way the HTTP protocol works.
As an example, if you are running a test with 100 concurrent clients
generally a configuration of 100 http threads is not going to be enough.
I would recommend atleast 200 or 250 connection in this situation.
I usually multiple the number of concurrent users you expect to handle
on a single server by 2 or 3 to allow enough connections to be available.
When modifying the number of threads you also need to keep in mind of
max thread settings as well. Check out the performance tuning guide for
more info, http://www.sybase.com/detail?id=1019504
The HTTP threads setting can be found on the General tab page for the
server properties.

| Maybe 1000 and 2000 is a bit too much. We have several servers in a
cluster to spread the load and we set each server to handle 350 http
threads, 350 iiop threads and max threads to 800 which seems to be fine.
