when testing I get more or less same message.

% This platform allows a maximum of 2 concurrent sessions with RX sources and

% 4 concurrent sessions with TX sources. (Bidirectional sources count as

% both RX and TX; remote VLAN sources count as RX.)

Try removing session you don't need or park it temporarily while you test.
