August 18, 20187 yr Hey Guys, been using unraid for about a year, I use it mostly as a media server with Plex. last few months the servers been having some issues with updating docker containers and restarting them also performance has been degraded. if anyone can help me figure it out would be much appreciated. This is the error I have in my log file, (my cpu is overclocked to 4.5 Ghz that's the only thing i can think causing the issue) Aug 18 11:43:14 Darkness kernel: mce: [Hardware Error]: Machine check events loggedAug 18 11:43:14 Darkness kernel: mce: [Hardware Error]: CPU 3: Machine Check: 0 Bank 0: 9000004000010005Aug 18 11:43:14 Darkness kernel: mce: [Hardware Error]: TSC 22e15bcc2f5e6 Aug 18 11:43:14 Darkness kernel: mce: [Hardware Error]: PROCESSOR 0:306a9 TIME 1534588994 SOCKET 0 APIC 6 microcode 1fAug 18 12:20:54 Darkness kernel: mce: [Hardware Error]: Machine check events loggedAug 18 12:20:54 Darkness kernel: mce: [Hardware Error]: CPU 3: Machine Check: 0 Bank 0: 9000004000010005Aug 18 12:20:54 Darkness kernel: mce: [Hardware Error]: TSC 235476b09f5e9 Aug 18 12:20:54 Darkness kernel: mce: [Hardware Error]: PROCESSOR 0:306a9 TIME 1534591254 SOCKET 0 APIC 6 microcode 1fAug 18 12:32:38 Darkness kernel: mce: [Hardware Error]: Machine check events loggedAug 18 12:32:38 Darkness kernel: mce: [Hardware Error]: CPU 0: Machine Check: 0 Bank 0: 9000004000010005Aug 18 12:32:38 Darkness kernel: mce: [Hardware Error]: TSC 23785547e2054 Aug 18 12:32:38 Darkness kernel: mce: [Hardware Error]: PROCESSOR 0:306a9 TIME 1534591958 SOCKET 0 APIC 0 microcode 1f if you need any more log info let me know.

August 18, 20187 yr Author I will go remove the overclock now see attach zip logs darkness-diagnostics-20180818-1519.zip
August 18, 20187 yr Author fixed it, memtest was clear, the overclock seemed to be the issue but that overclock been on for 2 years without any issues QQ time to move to duel Xeons I think! Thanks for the suggestions. Droven

Thanks for the suggestions. Droven More than one machine gets worse with time - capacitors etc on the motherboard ages and gets less capacity. So more noise on the power rails because of worse filtering. On top of that, also processors ages. Temperature and currents are important factors, and overclocking normally runs higher currents. High currents and temperatures can lead to electromigration. And besides that, some processors can get problems with the thermal paste drying up. An important thing is that there aren't really anything like "stable" when you overclock. You reduce the safety margins. And every second, the machine throws lots of dices - if they all end up 6+6+6+6+6+... then the machine goofs. The less margins you have, the larger probability that the dices will end up badly and the machine will goof. Just that most of the time, you will not notice anything bad because a large part of the memory and data processed aren't critical. So the machine might serve a micro-glitch in some MP3 sound or a video. But sometimes, the glitch makes the machine write a broken file to disk. Or make the machine break the file system. Or makes a program crash. When gaming, people may be fine with a program crashing once every two weeks. With a file server, it's best if it never fails.
