Log are frozen sometimes when i try to activate nodered system logs

to debug i m using debug nodes and sometimes i have activated the system logs to logs informations in logs file.

i observe sometimes the informations are not printed in the logs . Is there a paliative solution for this or advice on this topic

What OS are you using?
Exactly how are you viewing the log?
Exactly how are you logging?
Does node red keep going as expected when the log stops?
