Hi Mauro, I find this interesting because I have seen the same behavior with ntpd crashes on my server. Time jumps forward one hour every time this has happened. However I'm not convinced it's the hardware causing ntpd to crash. I don't understand why ntpd process exiting silently would allow the jump either, I would expect it to drift a few seconds over time, but one hour exactly every time?! Even with monit in place, within the two minute window that polling takes place and ntpd has crashed, before monit automatically starts ntpd, time is forward an hour. Do you happen to run a SuperMicro 5016T-MTFB¹ or a simlar board with an IPMI/baseboard management controller? ¹ http://www.supermicro.com/products/system/1U/5016/SYS-5016T-MTF.cfm -- Gerald Turner Email: gturner@unzane.com JID: gturner@unzane.com GPG: 0xFA8CD6D5 21D9 B2E8 7FE7 F19E 5F7D 4D0C 3FA0 810F FA8C D6D5
