Problems with deep sleep mode on IMX8M Mini EVK?

Hi,
I am developing on IMX8M Mini EVK running Android OS 9. I set the deep sleep mode with the command:
echo mem > /sys/power/state
However, when the system enters this mode, the console displays the following message every 60 seconds:
[   91.514416] PM: suspend entry (deep)
[   91.518110] PM: Syncing filesystems ...
[   91.549101] done.
[   91.551496] Freezing user space processes ... (elapsed 0.002 seconds) done.

[   92.612077] OOM killer enabled.
[   92.615225] Restarting tasks ... done.
[   92.620394] PM: suspend exit

Is the system working properly in this mode? Why is this message available every 60 seconds?
Can someone show me How to fix this problem?
Thank you very much!

Hello,

Could you please try to enter into deep sleep mode whit the Android interface?

Put Android to sleep for testing - Stack Overflow

However, this seems to be a normal behavior.

Best regards,

Diego.
