First, you don't need to specify ISC_SOCKET_FDSETSIZE in 9.3.6 (but I
don't think it's irrelevant to the main point).

Second, I have no idea.  Maybe it's somehow related to this change:

2472.	[port]		linux: check the number of available cpu's before
			calling chroot as it depends on "/proc". [RT #16923]

hopefully someone more familiar with Linux has some clue.
