Note: The version number should be changed in the below command as per the requirement. Ex: 2.5 or 2.8

1) /var/lib/gravity/planet/docker/overlay2 directory: 

( If Inside gravity try the path with /etc/docker/overlay2 )

find /var/lib/gravity/planet/docker/overlay2/ -type f -iname "*log4j-core-2.13*.jar" | sort | uniq > /tmp/log4j-jar-list.txt; for i in $(grep -Eo "[[:alnum:]]{63}" /tmp/log4j-jar-list.txt | uniq); do docker ps -qa | xargs -I{} bash -c "docker inspect {} | grep -q $i && echo {}"; done | xargs -I{} bash -c "docker inspect -f $'{{.Name}}\t{{.GraphDriver.Data.UpperDir}}' {}"

1) Please have the developer open their app's project in Studio.
2) Then, open a terminal to the app's workspace directory.
3) Follow the commands in this article to identify which component in that app is referencing the old log4j JAR: How to display the project dependencies and libraries of a Mule application with Maven
4) Mitigate and redeploy app.

If apps are not running:
1) Please follow directions from this article: Nodes running out of disk space in APCE because of /var/lib/gravity directory
