We are randomly getting "The host's NTP service is not synchronized to any remote server."   These alerts  then are being fixed by themselves, and the cluster reports that "The health test result for HOST_CLOCK_OFFSET has become good"   We are using chronyd. When I run 'chronyc sources' , I see two NTP servers listed, with ^* in front of the first one.   MS Name/IP address Stratum Poll Reach LastRx Last sample =============================================================================== ^* ipsap01.ecb.de 2 10 377 371 +40us[ +85us] +/- 8566us ^+ ipsap02.ecb.de 3 8 377 58 +31us[ +31us] +/- 14ms   The only thing I found in  cloudera-scm-agent.log file was this: [root cloudera-scm-agent]# catcloudera-scm-agent.log.1 | grep chronyc [13/Nov/2019 14:35:26 +0000] 58865 Monitor-HostMonitor throttling_logger ERROR Timeout with args ['chronyc', 'sources'] Exception: timeout with args ['chronyc', 'sources'] [13/Nov/2019 19:15:24 +0000] 58865 Monitor-HostMonitor throttling_logger ERROR chronyc: chronyc sources: not synchronized to any server [14/Nov/2019 08:19:25 +0000] 58865 Monitor-HostMonitor throttling_logger ERROR (11 skipped) chronyc: chronyc sources: not synchronized to any server [14/Nov/2019 12:36:26 +0000] 58865 Monitor-HostMonitor throttling_logger ERROR (1 skipped) chronyc: chronyc sources: not synchronized to any server [14/Nov/2019 14:36:26 +0000] 58865 Monitor-HostMonitor throttling_logger ERROR (3 skipped) chronyc: chronyc sources: not synchronized to any server [14/Nov/2019 18:17:28 +0000] 58865 Monitor-HostMonitor throttling_logger ERROR chronyc: chronyc sources: not synchronized to any server [14/Nov/2019 19:03:26 +0000] 58865 Monitor-HostMonitor throttling_logger ERROR (3 skipped) chronyc: chronyc sources: not synchronized to any server   What could be the problem?         ...
