B4J Question Jserver Background worker lost if task is put to sleep

[Num3]

Hello all,

I am coding my first jserver, where i have a background worker pooling data every 20 minutes.
It is running on a Linux Synology server.
This morning i noticed it stopped pooling the data and went to check the nohup.out log and noticed it stopped at midnight.
From the log attached i deduce the linux server put the jServer task to sleep and woke it up when i requested a page this morning, but the background worker is not running anymore.

My two questions are:
a) Is there a way to detect the server waking the task and rerun the background worker?
b) If not, can i force the server task never to go to sleep?

** EDIT **
I just noticed the background sync task did not report the done state after 23:54:24, i will further investigate this, has it could be a coding error.

The server process should never be paused.

I have a feeling that it is a coding error.
