Very strange. I'm pretty sure that cache itself cannot lock the GUI. For comparison, on my RT-AX56U, which has 512MB of RAM, with the latest firmware installed that has the same cache behavior as the current AX86U firmware (that is, cache is not cleared immediately as it was in the previous firmwares), I often see up to 90% RAM usage after heavy Samba usage that is freed maybe only in a day or two. And I have never experienced any GUI lockups or crashes (and that's after copying some backups that are about 30gigs in size). On the contrary, I find this cache behavior more natural and resulting in better stability.Well, so much for everything working well... Just tried to copy to/from the USB2 SanDisk thumbdrive formatted with FAT32. Faiiled on both and router GUI locked up.
