             Summary: when client is scaled down with in-doubt transactions, tx participants on server are resolved with delay
                 Key: WFWIP-222
                 URL: https://issues.jboss.org/browse/WFWIP-222
             Project: WildFly WIP
          Issue Type: Bug
            Reporter: Martin Simka
            Assignee: Ondrej Chaloupka
         Attachments: tx-server.log

this follows up on WFWIP-206

While testing tx recovery in OpenShift I see that when client is scaled down with in-doubt transactions, tx participants on server are resolved with delay.

Scenario:

*ejb client* (app tx-client, pod tx-client-0):
* EJB business method
  ** lookup remote EJB 
  ** enlist XA resource 1 to transaction
  ** enlist XA resource 2 to transaction
  ** call remote EJB

*ejb server* (app tx-server, pod tx-server-0):
* EJB business method
  **  enlist XA resource 1 to transaction
  ** enlist XA resource 2 to transaction

*testTxStatelessClientSecondPrepareJvmHalt*

JVM on client crashes in PREPARE phase of second XA resource on client. Then openshift restarts pod, but pod is immediately scaled down. Transactions on client pod are rollbacked during scale down, but on server they are rollbacked some time later. I'm not sure if it is periodic recovery or tx timeout.

server log with {{com.arjuna}} trace attached. 

Feel free to reject if it is expected behavior.
