Java App Stopped by OS

My Java app running on Linux seems to be stopped by the OS after around a day or so. There're no indication in my app's logs that it met a fatal error and quit by itself. Incidentally, my Java app is usually started from PHP, i.e. "exec".

Is there a reason to know why the OS kills the Java app process? Is there a way for the Java app (or JRE) to intercept the OS' signal?
