On Application Discovery, while running analysis, connection to Orient DB server cannot be established anymore. It seems all incoming connections are rejected due to a maximum number of concurrent connections.

In Application Discovery, when you reach maximum available connections in OrientDB, the server will not allow new connections.
The default value can be changed by means of property network.maxConcurrentSessions like this:
in conf/orientdb-server-config.xml
<properties>
<entry value="true" name="profiler.enabled"/>
<entry value="info" name="log.console.level"/>
<entry value="fine" name="log.file.level"/>
<entry value="2000" name="network.maxConcurrentSessions"/>
</properties>
When changing the network.maxConcurrentSessions setting as specified in https://orientdb.com/docs/2.1/Configuration.html, the maximum number of sessions accepted by the server concurrently can be changed. This allows tuning the server according to the user's needs.
