This message displays when at least one task is active and another task is in the process of starting up. The PowerExchange Listener port is blocked while a task is starting using an SSL connection until it has completed the SSL_accept() command, which upgrades the socket to an SSL connection.
The starting of SSL tasks can takes several seconds depending on the network, the number of certificates, and the CPU power of the client and server machines.
In the message text:
number
is the number of active tasks.
ports
are the ports of the starting tasks.
The PowerExchange Listener displays another informational message when the number of active or starting tasks changes.
