-----------------------------------------

             Summary: Session draining broken: requests counting broken on load-balancer
                 Key: MODCLUSTER-383
                 URL: https://issues.jboss.org/browse/MODCLUSTER-383
             Project: mod_cluster
          Issue Type: Bug
    Affects Versions: 1.3.0.Alpha1
            Reporter: Radoslav Husar
            Assignee: Jean-Frederic Clere
            Priority: Critical
             Fix For: 1.3.0.Alpha2


The request counting is broken. Looks like synchronization problem with dirty cached reads.

Steps to reproduce:

# start AS with some context
# start LB
# start 2 or more load driver threads
# number of requests on that context goes to higher values than 2, eventually and slowly increasing

On the AS it manifests as:

{noformat}
19:44:14,160 WARN  [org.jboss.modcluster] (MSC service thread 1-7) MODCLUSTER000022: Failed to drain 57 remaining pending requests from default-host:/clusterbench within 10.0 seconds
{noformat}
