1) do you have some scheduled process that deletes the catalina.out every 45
days? usually in linux, when logger open a file and some other process
deleted the file, it will not create new file, which i suspect the case in
catalina.out
2)  probably combined with some part of code swallowing fatal error like
such as permgenspace out of memory, you will not anything in catalina.out
