You can probably also remove
manageiq/app/models/miq_worker/runner.rb
Line 358 in 4a0ec8c
Otherwise looks good 👍
https://bugzilla.redhat.com/show_bug.cgi?id=1438935 For testing in e21d1b9, @worker_monitor_drb was changed to use the method. Unfortunately, this method isn't a reader, so it would create a new drb client each time it was called. It doesn't make sense for this method to make a new drb client each time, so we can cache this client on first access so it functions like a attr_reader now. We can then remove some memoization/caching that occurs in heartbeat since the getter method handles that for us.

@gtanzillo Making this a blocker since it floods the logs. Additionally, it creates a new DRb client each time we process a queue message, so it needs this PR fix. |
