Hi

I am trying to implement session replication: Followed these docs http://books.zkoss.org/wiki/SmallTalks/2007/April/HowtoRunZKonApache%2BTomcatclustering,PartI http://books.zkoss.org/wiki/SmallTalks/2007/May/HowtoRunZKonApache%2BTomcatclustering,PartII

In addition I am using <listener><listener-class>org.zkoss.zkplus.cluster.ClusterSessionPatch</listener-class></listener> in zk.xml

I have apache httpd as LB and tomcat 7.0.57 (two workers)

It works great sometimes, but often throws this error in catalina.out

SEVERE: Manager [localhost#/menubuilder]: Unable to receive message through TCP channel java.lang.IllegalArgumentException: Session id mismatch, not executing the delta request

After this error everything breaks and app behaves in strange way.

Thanks for help in advance AJaidka
