Any idea why i am seeing this gunicorn behaviour?

[pajod]

I see nothing in your report pointing to the trigger. Bisect or attach a debugger to find where this is from. Try a worker class other than gevent first, as that is a likely candidate for unexpected interactions.

If one of your imported python (extension) libraries does funny stuff and gets killed by the system, there is little gunicorn can do about it.
