-----------------------------------
Summary: CLONE - Remote EJB clients hanging after EJBClient.createSession
when using DIST
Key: AS7-4882
URL: https://issues.jboss.org/browse/AS7-4882
Project: Application Server 7
Issue Type: Bug
Components: Clustering, EJB
Affects Versions: 7.1.2.Final (EAP)
Reporter: Radoslav Husar
Assignee: jaikiran pai
Priority: Critical
Fix For: 7.1.3.Final (EAP)
We are seeing that in stress tests (positive test, no failures), the clients hang when
using DIST mode; both SYNC and ASYNC.
The clients hang in method [1]; there is nothing suspicious on the server side. [2]
The client has no knowledge about repl/dist topology, thus this should be a server-side
issue.
As of filing, we are investigating the issue.
