As of today, rsocket questions are best directed to linux-r...@vger.kernel.org 
(copied).  That goes for libibverbs based questions as well.  Rsockets is 
intended to mimic standard socket calls, so any socket based man page is 
relevant.  There is an rsocket man page which provides a small amount of 
additional details.  See

https://linux.die.net/man/7/rsocket

Of course, none of that tells you where to go with questions...

There are a couple of example programs provided with rsockets.  Are you able to 
run 'rstream' successfully?

Without knowing more details about your code, it will be really hard to figure 
out what is wrong.  The following link _might_ help in case you have 
restrictions on how much memory can be locked down on your system:
