nice to get your feedback @timosir
would you mind show us your code ?
as your description in the issue, i found you add the task 'tasks.sub3', however, in my add_task.py there's only 'tasks.sub' exists not 'tasks.sub3', have you ever change the code?

from redisbeat.

yes,i change your code.
add_task.py
#!/usr/bin/env python

encoding: utf-8

from datetime import timedelta

from redisbeat.scheduler import RedisScheduler

from tasks import app

if name == "main":
schduler = RedisScheduler(app=app)
schduler.add(**{
'name': 'sub-perminute2',
'task': 'tasks.sub3',
'schedule': timedelta(seconds=3),
'args': (99, 100)
})

task.py
@app.task
def add(x, y):
return x + y

@app.task
def sub(x, y):
return x - y

@app.task
def sub1(x, y):
return x * y

@app.task
def sub2(x, y):
return x * y

@app.task
def sub3(x, y):
return x * y
