Same thing happened to me when I upgraded from 4.3.59 to 4.3.76 or
4.2.8p4. I mentioned this on IRC (#ntp on freenode), and Harlan
replied that something changed, and now a memlock value of -1 means
"don't lock" and 0 means "lock whatever we need". My ntpds have been
stable for several hours now with -1.
