---------------------------------
> Possible load-balancing issue in Teiid
> --------------------------------------
>
> Key: TEIID-1453
> URL: https://issues.jboss.org/browse/TEIID-1453
> Project: Teiid
> Issue Type: Bug
> Affects Versions: 7.1.1
> Reporter: Boris Belovic
> Assignee: Steven Hawkins
> Attachments: ConnectionWorker.java, LoadBalancingServlet.java, teiid-ds.xml
>
>
> I have 2 SOA-P servers clustered, both with Teiid installed.
> node1 has property org.teiid.sockets.maxCachedInstances set to 2
> node2 has property org.teiid.sockets.maxCachedInstances set to 16
> There is a web app deployed on node1 which starts consuming connections from Teiid datasource. When all connections from node1 are used, the app should get a connection from second node. But instead , I have got following exception:
