Sorry if I was confusing in my post, sort of got ahead of myself but I mentioned nothing about deleting any log files. Generally speaking, a restart should have nothing to do with deleting and reinitializing most log files, a few, yeah, but not many and even they it's put into append not overwrite mode. I specifically mentioned garbage collection which is a different issue and more involved that I have the energy to explain...haha, yeah, I'm feeling THAT lazy today.
But my observation is all devices need periodic restarts everything from servers to cell phones. It has to do with garbage collection and memory fragmentation. In fact most so called "re-installs" of an OS are actually just restarts and system cleaning once the techs get your systems into the back room. Especially true of systems brought in with what are really phantom malware infections. Odds are there is NO malware just the system has not been properly setup to keep itself in proper order.
