What do you use to balance the load between the apaches ? Some things you have to keep in mind: - mod_jk isn't perfect in balancing the load for one Apache The workers don't know enough of each other to do a good job. - mod_jk is even worse in doing a good job in balancing the load on seperate apaches on different machines. The worker know even less (or nothing) about the other workers in the other apache instances.
Do you use sticky sessions ? When you see high load on the 2 instances do they have a proportional number of sessions (or is each sessions causing more load than usual) ? > -----Original Message----- > From: Arnab Chakravarty [mailto:[EMAIL PROTECTED] > Sent: Thursday, November 13, 2003 10:07 PM > To: [EMAIL PROTECTED] > Cc: [EMAIL PROTECTED] > Subject: Production Issues > > > 4 Solaris boxes - Each Box has 1 Apache - 3 Tomcats making 4 > apaches and 12 tomcats in all.
