Components: Virtual Router Affects Versions: 4.3.0, 4.4.0 Reporter: Sheng Yang Assignee: Sheng Yang Priority: Critical Fix For: 4.4.0 ntpd in VR can change time backward to sync with remote NTP server. But the check_heartbeat.sh for keepalived process in RvR depends on time to know if keepalived keeps writing to heartbeat file. ntpd rewinds the time result in check_heartbeat.sh misjudge the situation thus stop the keepalived process. -- This message was sent by Atlassian JIRA (v6.2#6252)
