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

We use the CLI to --force overwrite the deployments on the domain controller.

I'm not sure if it makes a difference, but we are in the process of migrating from Tomcat to WildFly, so we are deploying WARs with Tomcat version numbers in the filename but resetting the name in the deployment command i.e.

deploy /usr/bamboo/xml-data/build-dir/41811987-43712537/services##20160504.0614-r66d0ca5f382826538ea28e24713b2f9abba3ec27.war --name=services.war --force

> We have some development Wildfly 10.0.0 servers running as slaves in a domain that frequently have WAR files redeployed. We have noticed that these slaves will often go offline after a redeployment of WAR files with the following stack trace:
