Job queue stuck on slave server

Hi all, I have a problem with a 2-server setup
The slave server does not elaborate the job queue from yesterday, when the disk goes to 100%
Today I have freed some space and rebooted the server but the queue is still there.
I set the logging in debug mode but no log
I can connect from the slave to the primary mysql with no problems.

Do you have some tips?
Thank you.
Denis

 

sorry for the auto-reply but I have some new info, enabled finally some log:

And then the process (manually stared) hangs...

Any idea?
Thank you again
