dcruff's post in Emby on Unraid keeps shutting down external access (outside of my LAN) was marked as the answer
It does appear that the problem is solved. I had to reboot the Netgear router and the Unraid server and now it has stayed up for a few hours, much longer than before.
dcruff's post in Syslog filled up 100% - Suggested reboot and forum support was marked as the answer
Well, since rebooting, the Log file is at 1%. Hopefully it was a one-off. And, I just updated the Emby Docker.
dcruff's post in Cache SSD is Unmountable: not mounted was marked as the answer
I just checked my shares on Unraid to add cacheing to my appdata and domains and saw that they already had their caches turned back on. Apparently, when I reformatted and mounted the SSD cache drive, it automatically turned the cache on for several of the shares. I'm still debating whether I want to use it for media library. I'm also a little bothered that it turned all of those shares to "Yes : Cache" without my doing so.
So far, it has been running smoothly though.
