Async data send means that there is not time guarantee for when the session is 
delivered. The session should not get lost without any error trace in the logs.
I am still debating whether to remove this feature all together, but I left it 
in for people to play with. I have not found a case where async is useful, but 
I am sure there is which is why it is still there. Most of the time people 
want to be ensured that the session gets replicated, that is when pooled mode 
comes in.

also, from experience, using mod_jk in high load can result in "lost" 
sessions, cause it sometimes messes up the request and looses the session id.
from my experience, pen (siag.nu/pen) works better as a load balancer

I strongly suggest to retry the same test with replicationMode="pooled" and 
see if you get better results. 
Pooled means that replication is synchronous, but on concurrent channels.
