Err yes. Make more channels in the client. But the blocking of publishers
is a global thing, in order to stop Rabbit running out of memory, and to
give it a chance to process load. You really have no choice but to sit
it out. I would recommend you try and measure the throughput you're
getting out of your disk drives. There may be some tuning that can be
done there (or just throw more hardware at the problem).
