Re: [chrony-users] Tracking lost but server selected

[ Thread Index | Date Index | More chrony.tuxfamily.org/chrony-users Archives ]


Strace'ing the daemon, excepting connections i run from the client, i only see 
this activity for hours: 

----------------------
select(6, [1 5], NULL, NULL, {2783, 75820}
) = 0 (Timeout)
clock_gettime(CLOCK_REALTIME, {1521307188, 980265551}) = 0
clock_gettime(CLOCK_REALTIME, {1521307188, 980640329}) = 0
clock_gettime(CLOCK_REALTIME, {1521307188, 980950442}) = 0
adjtimex({modes=ADJ_FREQUENCY|ADJ_TICK, offset=0, freq=-2415664, maxerror=16000000, esterror=16000000, status=STA_UNSYNC, constant=2, precision=1, tolerance=32768000, time={1521307188, 981261}, tick=10000, ppsfreq=0, jitter=0, shift=0, stabil=0, jitcnt=0, calcnt=0, errcnt=0, stbcnt=0}) = 5 (TIME_ERROR)
clock_gettime(CLOCK_REALTIME, {1521307188, 981697915}) = 0
select(6, [1 5], NULL, NULL, {9999, 999252}) = 0 (Timeout)
clock_gettime(CLOCK_REALTIME, {1521317189, 82886363}) = 0
clock_gettime(CLOCK_REALTIME, {1521317189, 83261558}) = 0
clock_gettime(CLOCK_REALTIME, {1521317189, 83577629}) = 0
adjtimex({modes=ADJ_FREQUENCY|ADJ_TICK, offset=0, freq=-2415665, maxerror=16000000, esterror=16000000, status=STA_UNSYNC, constant=2, precision=1, tolerance=32768000, time={1521317189, 83888}, tick=10000, ppsfreq=0, jitter=0, shift=0, stabil=0, jitcnt=0, calcnt=0, errcnt=0, stbcnt=0}) = 5 (TIME_ERROR)
clock_gettime(CLOCK_REALTIME, {1521317189, 84323852}) = 0
select(6, [1 5], NULL, NULL, {9999, 999253}
----------------------

I can get much out of it, but it seems clear that the failing 
adjtimex() call is either cause or consequence.
