beta: lve-utils 1.3-12

One of the causes for CLN downtime this week was release of lve-utils 1.3 on October 1st. That release introduced a license check that would run via cron job every 12 hours. The way it was implemented - it would run every 12 hours on the hour. So we had significant spike on the hour, every hour. Due to differences in timezones it was spread around -- but we had big enough concentration of servers in two time zones that would sometimes cause overload of the CLN. That in case created cascading problem, as servers licensed by IP would try to re-license, which would significantly add to a load problem. The problem snowballed this Tuesday, causing CLN downtime.
While we are adding safety checks and optimizations into CLN, we want to also fix this cron job issue in lve-utils.
Now, when cron job is installed, the time to run is randomly selected. We also switched to one check per day instead of to.

  • Randomly select the time to run cloudlinux-cron cronjob
  • Spec file clean up
To update to new version of lve-utils, please, run:
$ yum update lve-utils --enablerepo=cloudlinux-updates-testing
