Infos:
- Used Zammad version: 4.0
- Used Zammad installation source: (source, package, …) package from APT
- Operating system: Ubuntu 16.04.
- Browser + version: Chrome
Expected behavior:
fetching mails regulary
Actual behavior:
Not fetching mails
System is very slow and creates high load.
Steps to reproduce the behavior:
Since some days fetching worked only after server restart.
Then I upgraded to Zammad 4.0
Ubuntu 16 with APT.
I was able now to fetch mails manual but I see these errors:
I, [2021-04-12T14:37:58.190263 #6435-47131396331940] INFO – : Checking left over delayed job #<Delayed::Backend::ActiveRecord::Job id: 192730, priority: 0, attempts: 0, handler: “— !ruby/object:Transaction::BackgroundJob\nitem:\n…”, last_error: nil, run_at: “2021-04-08 10:26:12”, locked_at: “2021-04-08 10:27:02”, failed_at: nil, locked_by: “host:euve269896 pid:13693”, queue: nil, created_at: “2021-04-08 10:26:12”, updated_at: “2021-04-08 10:26:12”> started.
And when I try to destroy I get this:
irb(main):001:0> Delayed::Job.find(192730).destroy
Traceback (most recent call last):

Your help is very appreciated.
