Look at your log: those clock drift events usually mean your system is bogging down for other reasons–usually a DB on the same box, or if a VM, the hypervisor starving your gateway.

thanks , I read the post for times ,but I have no enough knowedge to understand it .I’m using win10,jave 8,ignition 7.9.12 ( 7.9.14 have same issue). here is my ignition.conf. should I make any change?

wrapper.java.additional.1=-XX:+UseG1GC
wrapper.java.additional.2=-XX:MaxGCPauseMillis=100
