Satellite6 performance issues every day after noon

Solution Verified - Updated -

Issue

  • subscription related requests (i.e. against candlepin) take significantly longer
  • candlepin consumes much CPU
  • after some random time (e.g. several tens of minutes), the problems disappear
  • the issue usually starts to happen every day after noon
  • the problems are getting worse over days, usually - tomcat restart alleviates the problems to some extent
