    [ https://issues.jboss.org/browse/WFLY-10813?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13664240#comment-13664240 ] 

Claudio Miranda commented on WFLY-10813:
----------------------------------------

[~obludik], I could not reproduce it either. See the attached standalone-full-ha.xml, I used the [activemq-rar-5.13.0.rar|http://repo1.maven.org/maven2/org/apache/activemq/activemq-rar/5.13.0/activemq-rar-5.13.0.rar] resource adapter with 26 deployments, 26 resource adapters (each ra mapping to a different deployment) and each resource adapter with a single connection and admin object.

Can you share a resource adapter configuration of your wildfly ? Is your resource adapter added as a module or deployment ?

> We have about 25 resource adapters set through CLI. When I want to display them in web administration console it kills the whole wildfly server - server is not responding and after several minutes it ends up with OutOfMemory error and server must be restarted. We've seen this issue since wildfly 10 (it was the first version we used). With only a few resource adapters it is not happening.
