Hello guys

I'm trying to setup a Tomcat cluster to be synchronous (default uses
channelSendOptions=8, which is asynchronous). Some time ago, I had issues
with session replication, I asked on this list, and using the configuration
channelSendOptions="6" solved my issues. However, now, during load tests I
can observe that the session is not replicated on all cases during load

Here is the only change I made from the default configuration:

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster"

On logs, I can see errors on "Error Msg":

Jan 25, 2016 2:52:10 PM
org.apache.catalina.tribes.group.interceptors.ThroughputInterceptor report
INFO: ThroughputInterceptor Report[
        Tx Msg:63301 messages

        Rx Msg:200000 messages
        Rx Speed:0.00 MB/sec (since 1st msg)
        Received:227.72 MB]

So, do you know other configuration that I should change in order to
mitigate this?
