Workflowengine: Overflow logs

Hello, i have a little instance with more than 150 users, so from yesterday i am getting this overflow of logs without reason, if someone can light me up the way or help to find the solution or the corresponding log, thank you.

Nextcloud version (eg, 18.0.2): 18.0.6
Operating system and version (eg, Ubuntu 20.04): OpenSUSe Leap 15.1
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.33
PHP version (eg, 7.1): 7.2.5

The issue you are facing: an overflow of log.

Is this the first time you’ve seen this error? (Y/N):Y

Steps to replicate it:

The output of your Nextcloud log in Admin > Logging: This is a fragment of a 7.4G log
