I believe it's a hardware issue, however I'm not sure what's going on. My backup server is usually powered off unless I am rsync'ing a bunch of data over to it. About half the time, the server won't boot up properly unless I remove the flash drive and rebuild it in Windows (I just copy everything to the desktop, format drive, re-copy files/folders, and run make_bootable.bat). Everything works great after that. Sometimes, the server will not allow me to rsync all my files over (it stops rsync with errors on the console about stale file handles). Hardware specs are in my signature for system name "Saidar." The flash drive I have was one purchased from Tom. I've never seen any error messages about flash drive errors when plugging the flash drive into the system, either. Not sure why rebuilding it causes things to work OK for awhile. I've ran memtest for about 6 hours, with no issues reported. Also, I just powered on my server and manually started a parity-check, and emhttp crapped out. I can't access the standard webGUI (I have Tom's new webGUI installed, but it was from a plg that was released awhile ago, webGui-latest.plg). I do have unmenu installed, and I am able to access that. Below are the most recent syslogs I have (the one named -Current is the one pulled from unmenu while the system is running with emhttp down), hopefully someone can give me an idea.

Remove the plg GUI. Set up the system with no add-ons. Use only the basic system as downloaded.
