A customer hit a case where under SMF they were unable to use a project to increase the file descriptor limit to over 64k. Upon investigation, Jerry had the following comment:

I have found the bug in usr/src/lib/libproject/common/setproject.c in the rctl_set() function. I have tested the fix and Robert is reviewing it. The problem is that we see the existing rctls and set teardown_basic and teardown_priv to indicate that we want to remove those existing rctls, but in the loop to remove them, the logic to delete the rctl is incorrect, so it only deletes the first one it sees, then fails to find the subsequent rctls.
