[Django]-Celery inspect shows worker offline when Concurrency value reached

I found a solution that fixed this issue. I changed my workers to threaded as opposed to prefork by submitting the -P threads argument to the invocation:

python manage.py celery worker -f c:\logs\celery.log -E -P threads -l info --settings=[proj].settings.production

I was then able to correctly inspect the workers even when they were running at their concurrency value. I did have to ensure that all of my tasks were threadsafe (shutil was the major offender, and a simple lock fixed it).

I hope this helps.
