Tomcat logs are not rotating in 18.4v

Hi ,

Please advise on how to enable rotatelogs for tomcat-stdOut.log file ? currently we are in 18.4v and tomcat-stdOut.log file is not rotating instead keeping same file with huge size.

we are using Linux box . rotate logs utility is present in the same box but still we were not able to see tomcat-stdOut.log file rotated. 

we updated start-appserver.sh script as well . 

Appreciate if anyone can help on this to enable rotate logs .

Please let me know if any utility or package should be installed for Linux box
