Dear All,

Apache 2.2
Apache tomcat 5.5
Sakai 2.8

I am using apache as load balancer. I have seen following error in apache
log many times.

I have searched on google and found following answer.

"The answer is that the request headers have to fit into 8Kb or the request
fails.
Looking at the failing request the cookie information is more than 8Kb. "

Does any one have found this problem in sakai load balancing.
