That's why I set swapiness to a low number. I don't want it to use swap unless it is to prevent a crash. If I set it to a higher number, it wants to use swap even when there is memory available. Once it starts using swap, it gets slow. The more it uses, the worse it gets. However, it beats it rebooting without umounting partitions and such. If nothing else, it may give me time to use the alt-sys sequence. I'm maxed out on memory at the moment but wish I could get and afford 64GBs, in a way. Still, I'd have a swap partition.
