z/OS has activated Optimized Latency Mode (OLM) for a connection through an OSA Express3 adapter.
This reduces the maximum number of concurrent connections per physical port for shared adapters.
The new connection would exceed the maximum. Linux cannot establish further connections using
this adapter.
User response
If possible, deactivate an existing connection that uses this adapter and try again to establish
the new connection. If you cannot free an existing connection, use a different adapter for the
new connection.
