After upgrading Eramba to version 3.30.0, we’ve received the below email in our inbox. Upon investigating further I found that this job (Diagnostics.Statistics) has been failing for a long time already.

Hello,

A background job in eramba has failed and was not re-queued automatically. This may require your attention.

Job details:

Job ID: 250534

Attempts: 1
Fetched At: 2026-06-02 00:42:23

Failure Message:

Please review the job and your system configuration to determine the cause. If necessary, you may need to retry the job manually or investigate related logs.

From a brief inspection of the code I think that there is actually no implementation of a class `NotificationSystemsItemsTable`. I’ve tried downloading and inspecting various eramba docker image versions, but could never find this class.

What can be done to solve this issue?  
Is it at least possible to disable the `Diagnostics.Statistics`task?

Thanks,  
R.
