             Summary: Avoid running out of threads when connecting to the DC from a slave to pull down missing data
                 Key: AS7-6809
                 URL: https://issues.jboss.org/browse/AS7-6809
             Project: Application Server 7
          Issue Type: Feature Request
          Components: Domain Management
            Reporter: Kabir Khan
            Assignee: Kabir Khan
             Fix For: 8.0.0.Alpha1


For AS7-6808 when a slave connects to the DC to pull down missing data, it does this by either getting a lock for the DC, or by joining the permit of the existing DC lock if the request to update a slave's server-config was executed as part of a composite obtaining a lock on the DC.

The way it works at present there is a thread per slave which is blocked until the transaction completes. The DC threads are a finite resource, so a large number of slaves trying to pull down dats will cause deadlock
