You could check which zones the IPC code in GNU Mach allocates for port related data structures. Somewhere in gnumach/ipc/. If you don't find it, get back to me, and I will have a look. Of course, the origin of a port leak is as easy or hard to find as the origin of a memory leak. Use portinfo to spot the task which a suspiciously high number of ports. If you can trigger the leak without crashing (ie, just leak a couple of dozen ports, then stop whatever you are doing that leaks), you can investigate the ports more with gdb and portinfo (what type of ports are they, etc).
