Re: tomcat 5.0.16 Replication

Well just to make sure that I wasn't saying something untrue. I went to 
check my redhats.

Everything DOES work fine but it's true that there is some loop 
somewhere because both my tomcat are having abnormal loadavg. ie:  1.15
even with the server are idle.

So everything works for you?

Currently running tomcat 5.0.16 with the CVS HEAD of the replication module.
This is under redhat 9. So far so good.
What kind of problem did you encounter under rh9?

my only experience with Redhat 9 is that it doesn't play well with NIO.
I have not successfully ran tomcat clustering on RH9, I use RH8.
I also don't have a RH9 machine at home yet, so I can't develop for it

I was having random problems with clustering when starting up.
   

Mostly it had
 

to do with Timing out
when the manager was starting up. I built the CVS version and it
   

solved that
 

problem. But it has caused
some serious performance problems.
First a little background.

I have 2 servers, dual 300mhz cpq proliants, both running Redhat -
   

9, Tomcat
 

5.0.16 (with catalina-cluster.jar build from cvs) The multicast packets are
restricted to a crossover link between the servers. There are 3
   

hosts in the
 

server.xml, all with clustering set up. They all function just fine.

But.....the cpu's spikes up to 100% if I start up both servers. I know this
didn't happen without the new catalina-cluster.jar. If I shut down 1 server
(doesn't matter which) everything returns to normal. But when both are
running both servers are at 100% CPU. I am trying to profile it now, but I
figured if someone has already experienced this they could save me some
time.
Oh, and there isn't anything relevant in my logs. It's not
   

throwing millions
 

of errors or something.
