Not quite. Reported crashes included 6.27, so it's possible that some other
mitigating factor helped not to crash (like using SNTP instead of NTP,
although there seems to be people with crashes using SNTP or no SNTP/NTP at
all).

These are running Linux kernels, right?  Anybody know which version?  I
know the last couple of leap seconds hit (different) bugs in the Linux
kernel.  The 2012 bug was timer related and confused some user-space
applications, but the 2008 bug could cause a kernel deadlock (which this
sounds like).
