I'm using Supervisor and the uWSGI Emperor mode. When I set limit-as to 512 (MB), workers die instantly (respawn, die, respawn, die, every 3/4 of a second or so):
[uwsgi]
workers = 4
threads = 40
limit-as = 512
harakiri = 20
max-requests = 1600
... non-performance/memory/processor-related settings ommitted
But, if I change limit-as to:
[uwsgi]
workers = 4
threads = 40
limit-as = 1024
harakiri = 20
max-requests = 1600
... non-performance/memory/processor-related settings ommitted
and restart uwsgi, the problem is gone immediately. In order to put a sham in this, I've modified the setting back to 512, restarted again, and the problem is back immediately.
Notes: My app is a simple Django app without much additional Python setup during start-up time.
