I'm working with django project, Recently i have hosted a new application in the apache2 server ,now apache2 is running with two application , both the django project are working fine. But frequently i get some error like "Maximum recursion level reached" and my application fails to work. please help me to find the problem.

Is this correct to point both the application towards same virtual environment(venv)

Answer 1

I had the same issue after i found this quick and dirty solution just increase the recursion limit in your python script:

sys.setrecursionlimit(1500)

Default is 951, if it's not working then i guess you need to look at the traceback for repetitive patterns

I hope it will be helpful to someone!
