[FC3] Ntp very easy to kill

Hi,
I just hit the very same problem. Whenever my server was included in
pool.ntp.org it died within hours.
After some hours of experimentation and research I think I have found
this problem to be a combination of
1) misconfigured clients using 'peer' instead of 'server'; use 'nopeer'
for all client access restrict lines
2) ntpd trying to lock itself into memory; compile ntp without
HAVE_MLOCKALL
3) RLIMIT_MEMLOCK is only 32kB by default; raise with ulimit -l before
starting ntpd
Tom
