depends on how it does the load balancing. If it only redirects the first then leaves the user on that server then a power users maybe causing the problem.
The other servers just seem to be getting the lower loads, lower users. Look at the logs of a period of time and look at if it is always server 2.. How does the server indicate to the load balancer that it is overloaded? Is it overloaded or just got more threads, less traffic but more threads? So many question few answers but i hope this helps. server seems busy? you need to look more on things like actual bandwidth and latency of pages on each page. Also it could be just a cheap load balancer and all it is doing is a rotation. not balancing. How long do you allow sessions to be kept open and do the sessions cross servers (Single signon) On Wed, Apr 23, 2008 at 11:13 PM, Sir June <[EMAIL PROTECTED]> wrote: > Hi, > in my previous thread x509, i mentioned i have 3 linux boxes with a load > balancer in their front-end.
