   Try "make clean" in the kernel build directory and building it
again.  It looks like sys/conf/files has flags for NKMEMPAGES,
KMEMPAGES_MIN, and NKMEMPAGES_MAX, but not NKMEMPAGES_MIN, which
would prevent the build from catching the config change. (I assume
this is a typo/bug. Unless someone wants to make a quick change,
I'll send-pr it.)

   Still, it sounds like you are running into a buffer leak, so
this might only buy you some time.
