[CRITICAL] Autosubmit couldn't set your experiment as running on the main database. Exception: database is locked[eCode=7003]

I am having the following error message for a while when running with AS3.13.0:

Starting job submission...
Creating jobs...
Loading JobList
Adding dependencies...
Removing redundant dependencies...
Using existing valid structure.
Checking scripts...
6 of 27 checked

Scripts check failed
 Running after failed scripts is at your own risk!
Autosubmit is running with v3.13.0
 [CRITICAL] Autosubmit couldn't set your experiment as running on the main database. Exception: database is locked[eCode=7003]
Checking the connection to all platforms in use
[marenostrum4] Connection successful to host mn-bsc32
[marenostrum4] Correct user privileges for host mn-bsc32

I have been ignoring it since it never prevented me to run my experiment but I am wondering from where it can come from... Could you tell me?

Thank you,

Yohan
