Unfortunately you haven't provided a great deal of information about
what you are doing in your tasks.
My guess is whatever you are running in the task is just taking too
long.
Queued will retry unless you exit cleanly. And each failed tasks time
between retries will
will increase.
You should put some logging in your task to see where it is getting
too. Then you will have some idea
where the bottleneck is.
The task queue subsystem is in my experience quite robust and reliable
if you
code you tasks taking into account its limitations.
