Sphynx has been telling me for a couple days now--quirkily, the length of time the really bad bugs have shown up for me--that it's a bad idea to keep caches for SL on a temporary drive. Or maybe on a small drive is better.
So, after crashing for the second time, and noticing yet again I couldn't drag anything into a prim (and this after not being able to buy things on several of the hunt stops, earlier) I finally started putting two and two together.
Having asked a question of the talented gentles in the Twisted Thorn group about that same time, Miss Barbara Collazo tossed me a way to sledgehammer caches.
She's not kidding. It really works.
And I'll tell you something else--it works whether you kill and relocate one cache, or--as I had to do--kill and relocate four.
All four caches (for SnowGlobe, CoolVL, Emerald and viewer 2.1, if anyone's curious) are now in a subfolder off C drive. It's not ideal--but nothing's pulling off my 2 gB flash drive, now.
Me? I'm just happy things work again.
Don't mistake me--large inventories still cause lag, and I'm, not begrudging the hour of panic that led me to deleting more than nine thousand inventory items. I need to do more work. There's just way too much stuph out there, one avatar cannot own it all. And an avatar who lives, works and builds? It's far too easy to accumulate mass tons of things.
But never put your SL cache on a small, temporary drive. Trust me. Things go sideways at speed.
