January 13, 20179 yr Hello, I am new to unRAID and Linux, so I was hoping to get some help with this. I built my server a few weeks ago, and everything is great, except that several nights in a row the server has become unresponsive and I have to do a hard reboot. When the server is unresponsive, I am not able to go to the web GUI with my server name, nor with the IP address. It just 'loads' forever and nothing happens. I can't access the network drive. I am not able to telnet into the server. And when I hook my server up to a monitor, the cursor is blinking, but I can't actually type anything. After the second time, I ran memtest overnight (around 12 hours) and it didn't come back with any issues. The server also didn't freeze that night, but it really wasn't running any processes. Last night, I used the Fix Common Problems plugin because I saw that it had troubleshooting functionality. I've attached the syslog and diagnostics from that. It looks like the server crapped out at 3:47AM. These are the last two lines in the syslog: Jan 12 03:47:34 HarrisonMS kernel: Out of memory: Kill process 4222 (Plex Media Scan) score 478 or sacrifice child Jan 12 03:47:34 HarrisonMS kernel: Killed process 4219 (Plex Media Scan) total-vm:2020540kB, anon-rss:1802196kB, file-rss:16kB The only apparent difference between last night when it froze and the night before when it didn't freeze is that last night I was downloading a TV series with SABnzbd. I'm not sure if that is what caused the memory issue and if the memory issue is what caused the server to "die". If so, what would I need to do in order to be able to download (either torrents or nzbs) overnight? If that isn't the cause of the freezing, does anyone have any ideas? I appreciate the help. syslog.txt harrisonms-diagnostics-20170112-0326.zip
January 13, 20179 yr Looks like you're running on 4G of memory. And Plex is basically killing the available memory everyday and triggering the system to kill off processes that haven't been used recently. Upgrade to 8G (or stop the background processes for Plex)

And Plex is basically killing the available memory everyday and triggering the system to kill off processes that haven't been used recently. Upgrade to 8G (or stop the background processes for Plex) Thank you for the quick response. It looks like I had Plex set to update my library whenever it finds a folder difference. So I'm assuming since I'm downloading 20+ TV episodes, it is scanning my library 20+ times each night. I will definitely change that to maybe only update hourly. I will also look into getting another stick of RAM. Fingers crossed that this is the solution.
