[Jack-Devel] Port number limitation

I have noticed the JACK server limitation of port numbers in some specific applications ("Maximum number of output ports is reached for application ref = 2"). I have noticed the "-p" / "--port-max" parameter and was able to artificially scale down or up the available number. But, I seem to have reached and upper limit at around 800. Due to possibly already existing ports like system input and output I am not certain of the exact number. To be fair, the available number is high enough for general use cases (also for me). But in these certain conditions it definitely limits my possibilities without an apparent workaround. Is there a way monitor if the port-max is passed correctly? Or where the limitation arises otherwise? Or how to possibly circumvent it? Best, /Hannes
