Every once in a while our catalina.out file gets very very large (yes, I will be implementing slf4j and logback in my applications to prevent this in the future). But for now, when I go to cycle the logs, I copy catalina.out to catalina.{date} and execute `cat /dev/null > catalina.out`. The problem is, tomcat will capture no further logs after I do that, until tomcat is restarted the next morning, and this is not ideal. Why does this happen? And is there a way to avoid it?
