In case when your installation has enabled debug/trace logs catalina.out file may overgrow very quickly.
Apache Tomcat is sensible to change of file descriptor of file catalina.out. So if catalina.out file has been moved or deleted Tomcat may stop working. To prevent tomcat restart and save logs you may use this solution.
Instructions
Run next bash command
cp catalina.out catalina.out.2020-12-03 && cat /dev/null > catalina.out
this will create copy of catalina.out file and then erase it.To compress backup file use for example gzip, run next command:
gzip catalina.out.2020-12-03
One thing to note that you must have enough of space on disk to create a copy of catalina.out.
