After upgrade 2.2.4 to 2.2.6 we can't create vlans. Just press add new vlan after some timeout we getting this error.
I found this https://stackoverflow.com/questions/8177073/python-maximum-recursion-depth-exceeded
but I'm not sure that is problem.
I'm not python expert.

No idea what would be causing it. What version of Django are you running? (You can check by running pip freeze | grep Django) It should be 1.11.

Hi @jeremystretch ,

I just played with different values of:

import sys
sys.setrecursionlimit(1100)

And put this lines on top in file /var/www/netbox.company.com/gunicorn_config.py

And now work fine.

Modifying the system recursion limit doesn't really fix this. But without being able to reproduce it I'm not sure what else to tell you. I'm going to close this out, but if anyone else happens across this issue please comment here and ask that it be reopened.
