Below is a config I think would make sense. Note that the core and max threads should probably changed, based on the number of channels you use over the shared transport.

{code:xml}
<subsystem xmlns="urn:jboss:domain:threads:1.1">
            <bounded-queue-thread-pool name="jgroups" allow-core-timeout="true">
                <core-threads count="4"/>
                <queue-length count="20000"/>
                <max-threads count="200"/>
                <keepalive-time time="10000" unit="milliseconds"/>
            </bounded-queue-thread-pool>
            <bounded-queue-thread-pool name="jgroups-oob" allow-core-timeout="true">
                <core-threads count="2"/>
                <queue-length count="1000"/>
                <max-threads count="20"/>
                <keepalive-time time="10000" unit="milliseconds"/>
            </bounded-queue-thread-pool>
            <scheduled-thread-pool name="jgroups-timer">
                <max-threads count="4"/>
            </scheduled-thread-pool>

> The JGroups subsystem needs optimal defaults out of the box, that are also good for derived products (e.g. JDG), both for protocols and thread pools.
> Use a bounded thread pool for the default executor
> core-size==number of members (32 for JDG)
> max-threads = 1.5*core-size
> oob should be queueless
