July 29, 20178 yr I noticed my server was lagging very heavily suddenly today and I couldn't access any of my dockers or even browse usershares. Even logging into SSH was very laggy. I tried to stop all dockers but the system was hanging. I managed to stop the array after waiting what felt like 30minutes. After stopping the array the system was quick to respond again, however when scanning fix common problems it showed some errors (See below). Please see the attached diagnostics unnas-diagnostics-20170728-2148.zip
July 29, 20178 yr Community Expert You might try installing the 'Tips and Tweaks' plugin. Then on the 'Tweaks' tab, turn on the 'Help' (button in the Header menu). Now set the "Disk Cache 'vm.dirty_background_ratio' (%):" and the " Disk Cache 'vm.dirty_ratio' (%): " to the the suggested Streaming and VM settings. (The default are probably OK for systems with less than a 2GB of RAM but a bit excessive for what most of us have in our servers! Plus, these defaults were setup originally to increase the perceived responsiveness of system where the user is actively working on the system desktop.)

I installed the plugin and changed the default values. Hopefully this fixes it
