@weizhouapache I created two schedules like below on a single VM and I am still seeing the DB Exception in the logs. The execution of the schedules is happening only one server now.

thanks @vishesh92 for testing

as discussed offline, it is a minor issue.
it seems to be because the the job is scheduled twice by the same management server . so this PR is incorrect

server: run the vm scheduler poll task on only one management server
