[jboss-jira] [JBoss JIRA] (WFLY-12404) High Fail rate with MOD_JK and JDG remote-cache-container

[Paul Ferraro (Jira)]

     [ https://issues.jboss.org/browse/WFLY-12404?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Paul Ferraro closed WFLY-12404.
-------------------------------
    Resolution: Rejected


These discrepancies would only be due to difference in configuration between the load balancers. e.g. what types of responses are eligible for retries, number of retries before workers are disabled, etc.

> Scenario: 2 nodes WildFly cluster where session data is offloaded to a remote 2 nodes JDG cluster (jboss-datagrid-7.3.0);
> When using MOD_JK as load balancer we observe a higher fail rate (~9%) than when using MOD_CLUSTER or HAPROXY (~0.9%); fail rate is intended as inconsistencies in the data stored in cache and subsequently retrieved on another node of the cluster:
