Hi,
We have been using Wildfly 8.2.0 domain cluster for a couple of months and we have experienced terrible stability problems particularly during deployments, redeployments and assignments... (BTW: it seems we are not alone, almost identical problems are described e.g. here).
It seems that there is a problem in domain controller or its management interface and it establishes a single point of failure (often something is deployed using the web interface, the deployment hangs and the whole cluster goes down).
We have decided to move to the solution using standalone servers connected to the cluster. It seems working well so far. But, of course, without domain there are certain issues to solve:
Thank you.
Tomas
