Tommasso Borgato updated WFLY-12669:
------------------------------------
Description:
The issue is about scattered cache replication across cluster nodes;
WildFly is started in clustered mode using a scattered cache for replicating HTTP session data across cluster nodes; all 4 nodes in the cluster are initialized with the following {{cli}} script:
{noformat}
embed-server --server-config=standalone-ha.xml
/subsystem=jgroups/channel=ee:write-attribute(name=stack,value=tcp)
/subsystem=infinispan/cache-container=web/scattered-cache=testScattered:add()
/subsystem=infinispan/cache-container=web:write-attribute(name=default-cache, value=testScattered)
{noformat}
The test is run with [wildfly-18.0.0.Final.zip|https://download.jboss.org/wildfly/18.0.0.Final/wildfly-18.0.0.Final.zip]; the same tests run with version [wildfly-17.0.1.Final.zip|https://download.jboss.org/wildfly/17.0.1.Final/wildfly-17.0.1.Final.zip] do not have any problem; hence this looks like a regression;
As usual, we test that the serial value stored in the scattered cache is incremented at every call: when this is not true, we say we have a *sampling error*;
Using MOD_JK as load balancer, we have a *22.46%* of *sampling errors* with wildfly-18.0.0.Final.zip (0% with wildfly-17.0.1.Final.zip):
