Hi, Thanks for your posting. The major concern of not using the whole file is not because of memory issue. I need to find a string in that file to determine whether application is running or not. If I restart the application multiple times, there will be multiple 'startup' string in this log, so that I only need last lines of the log when its size is not increasing anymore.
