Having the exact same issue, looking at your previous thread my diagnostics even freeze on the exact same line as yours does.. I've found similar threads, but this is the only one I have seen with almost the EXACT same symptoms as mine: df -h hangs, cant access anything on /mnt/, docker containers stuck and cant be stopped/removed/killed (shows execution error in webui), etc. WebUI also shows multiple cores pinned at 100%, but htop doesn't show that much usage. It's driving me insane. Syslog also shows no relevant info or errors. The only way to make the server usable again is to hard reset it, which obviously isn't good to be doing every day at this point. Mine can hang at (seemingly) random, but for me it also happens when I start loading lots of content on one of my docker containers, LANraragi. I can easily recreate the issue without having to wait on random chance by spam opening galleries on there for about a minute until LANraragi's webui stops serving me images, which leads to /mnt/ hanging and becoming inaccessible. I've replaced my docker img file and reinstalled all my containers from scratch, but the problem persists. All my permissions look fine. What docker containers are you running? Anyways, I am at my wit's end with this issue. Currently running a memtest to see if it's RAM related, and my next step is running extended SMART tests on all my drives if I run out of other, less time-consuming ideas. I'd attach diagnostics now, but like I said earlier it keeps freezing on a certain line, the "sed" command that ends with /shares/appdata.cfg 2>/dev/null I'll grab diagnostics from a clean bootup after I finish running memtest, and also check the flash drive for any partially completed diagnostics.
