Error while killing gevent.greenlet

[Ayush Pratap Singh]

My application uses gevent 22.10.2 tand greenlet 2.0.2

It is a TCP server which spawns 3 gevent.greenlets.

During disconnection flow when the code tries to kill the greenlets it throws an exception "Cannot convert greenlet.greenlet to gevent._gevent_c_greenlet_primitives.SwitchOutGreenletWithLoop" 

It occurs occassionally, say 1 out of 10 times.

This is how I'm creating and killing greenlets.

//Create

routine = gevent.spawn(Routine)

//kill

if routine:

    if not routine.dead:

        routine.kill() // exception thrown from here

    routine = None

These routines are also not blocked anywhere when kill is called.

 

Perhaps I'm doing something wrong?
