Python Module Threading Issue

[Gary Gwin]

Hi Arran,

I built 3.0.18 from the master branch and reproduced the same concurrency
issue. The issue manifests under a small load with config of multiple
modules in multiple sites. I didn't know how to provide the full context
here:

https://github.com/FreeRADIUS/freeradius-server/tree/master/src/tests/modules/python

I minimized my test case and changed the naming conventions to match. I've
attached:

1) modules.conf - which can probably be appended to modules.conf in the
repro
2) mod7.py - minimized Python code to use
3) test-small.csv - test accounts to use with radperf

To configure in the default raddb config:

1) sites-enabed/default - add 'mod7_default' before chap in authorize
2) sites-enabled/inner-tunnel - add 'mod7_inner_tunnel' before chap in
authorize
3) mods-enabled - I'm sure you know what to do better than me

Run:

1) ./radperf -s -p 10 -D stats.out -f test-small.csv 127.0.0.1 auth
testing123

Run radiusd as a service. The issue does not manifest running "radiusd -X".

Please provide more instructions if you want me to do more to integrate
into the Python test environment.

Thanks,

Gary
