Environment

  • Python version: v3.5.2
  • NetBox version: v2.4.6

Steps to Reproduce

My users are reporting that they get intermittent errors deleting or manipulating objects.
They get those errors for a couple of minutes and after a couple of minutes the delete operations working fine.

Expected Behavior

The operation should not produce a internal server error.

Observed Behavior

Please find the error info generated when this happens.

Internal Server Error: /dcim/devices/1560/delete/

ValueError at /dcim/devices/1560/delete/

The problem is i cannot re-create the issue on demand ... yet.
I just have a lot of user complaints and get around 10 to 15
errors a day like the above mailed to me on a mildly used installation.

So during normal operations from time to time my users get a server error like the above
when deleting objects or inventory items.

Re-opening this because it's the earliest report of a symptom which I believe is related to somewhat-randomly recurring bug. It seems that the changelog middleware has been running into the issue described here, where the user associated with the request is not authenticated prior to being captured for the ObjectChange being recorded.

In an effort to document our findings, we noticed develop-2.6 is not experiencing this issue. I ran an overnight endurance test to confirm this. The code changes we tried in #3081, unfortunately, did not work so we investigated what is different in develop-2.6. Upgrading the Django dependancy to 2.2 is only noticeable change so I reran my endurance test again with 2.2 in develop with great success.

At this point, we don't have a root cause but we know upgrading to Django 2.2 fixes the problem. Unfortunately, the release notes, don't seem to mention anything related.

So the question is do we pin develop to Django 2.2 or match the looser dependancy defined in develop-2.6? @jeremystretch do you know of any other Django changes that would make this problematic?

I don't believe upgrading to Django 2.2 required any changes to NetBox. I think it's reasonable to have the 2.5 train match Django>=2.2,<2.3 to fix this issue.

I think this bug still exists in 2.6.1. I found intermittent failure in Delete operations.
